TG-DTA OR TG-DSC TECHNIQUES FOR THE STUDY OF THE SYNTHESIS OF OXIDES BY THE SOL-GEL METHOD

Sol-gel is the abbreviation of solution-gelation. Sol-gel synthesis is used in materials science to produce solids (metal oxides) from small molecules (typically metal alkoxides) and is similar to a polymerization reaction. A macromolecular network of oxides is fabricated during the hydrolysis and condensation of molecular precursors. It involves the conversion of the precursors into a colloidal solution that is converted into a gel of either discrete particles or network polymers.

Then the remaining liquid phase (water and solvent) is dried and a thermal treatment is often necessary to improve the characteristics of the final material. Dopants like organic dyes or rare earth elements can be added to the precursor in the solution and thus be dispersed in the material. The sol-gel process is considered as a cheap and low-temperature alternative to other synthesis techniques involving materials melting.

The final materials can be applied to optics, electronics, energy, gas sensors, biomaterials…

SIMULTANEOUS THERMAL ANALYSIS

Thermogravimetry coupled to Differential Thermal analysis or Differential Scanning Calorimetry is a long time proven method to study thermal processes. It is mostly applied in the field of sol-gel synthesis to determine the temperature ranges of interest during the drying and thermal treatment phases.

A typical TGA thermogram corresponding to the heating of a gel under controlled rate exhibits a multiple steps mass loss corresponding to the evaporation of water and organic solvents. The DTA or DSC signal will exhibit endotherms due to evaporation or exotherms when the evaporating solvents decompose or oxidize. At higher temperature an exotherm not linked to any mass change is observed, corresponding to the crystallization of the synthesized amorphous material. Depending on the desired final product, this crystallization temperature may be a limit to overcome or not.

The MFP-3D Infinity™ AFM

April 16, 2014 – Oxford Instruments Asylum Research Introduces the MFP-3D Infinity™ AFM
Featuring Powerful New Capabilities and Stunning High Performance 
April 16, 2014 (Santa Barbara, CA)  Oxford Instruments Asylum Research announces the new
MFP-3D Infinity Atomic Force Microscope (AFM). The MFP-3D Infinity is the new flagship of the Asylum Research MFP-3D™ AFM family with dramatic performance improvements, new nanomechanical measurement capabilities, and new features that make it simple to get started with tapping mode imaging. Whether you are doing routine imaging tasks or ambitious research projects, the MFP-3D Infinity is ideal for an endless variety of applications with unlimited potential for
your research.
“The MFP-3D Infinity has evolved extensively from the original MFP-3D that pioneered closed loop scanning and low noise AFM measurements,” commented Dan Bocek, Project Manager. “The development team used their superior knowledge of AFM physics and technology to accomplish truly remarkable performance improvements. We reduced the XY sensor noise by 70% and slashed the Z sensor noise by more than 85%. Overall system height noise is now only 20pm, a third of what it was on the original MFP-3D. The practical benefit is that our customers can now achieve higher resolution while still enjoying the unmatched versatility of the MFP-3D family. No other AFM beats this combination of performance and flexibility.”
Jason Bemis, Manager, High-level Software, added, “We’ve also introduced new software features that showcase the potential of this new hardware and enhance the capability and greatly improve the ease of use of the new Infinity AFM. Our new Fast Force Curve Mapping mode enables the high speed capture and analysis of force-distance curves. We’ve also developed a new feature called GetStarted™ that does exactly what it says. It helps users get high quality tapping mode images from the very start.”
The MFP-3D Infinity features a large 90µm stage and entirely new control electronics that are located close to the AFM for fast, low noise performance. Flexible signal switching and programmable logic enable future expansion options. The new head and scanner offer greatly improved sensor noise (<35pm in Z and <150pm in X&Y) and higher bandwidth for improved force control and faster imaging. Top and bottom view optics provide a large field of view and diffraction-limited resolution for pinpointing features on your sample.
GetStarted greatly increases AFM productivity. It is an intuitive new feature that automatically sets tapping mode imaging parameters such as setpoint, gain, and scan rate based on your sample roughness and cantilever calibration. Unlike iterative optimization schemes, GetStarted uses a robust predictive algorithm so that accurate data is produced from the very first scan line without the potential of tip and sample damage that is common with other optimization routines that assist with scanning.
The new Fast Force Mapping mode brings Asylum’s market leadership and expertise in force spectroscopy to fast force-distance curves measurements. Operating at up to 300Hz pixel rate, it captures every force curve in the image without missing curves or performing hidden data manipulation. Realtime and offline analysis models calculate modulus, adhesion and other properties, and are user-accessible. Part of the NanomechPro™ Toolkit, Fast Force Mapping is a technique complementary to AM-FM Viscoelastic Mapping mode and Contact Resonance Viscoelastic Mapping Mode.
The MFP-3D Infinity remains compatible with the full range of MFP-3D accessories. No other AFM in the world supports such a wide range of innovative accessories, both practical and unique, for temperature and environmental control, controlled gas or liquid environments and for experiments using external driving forces – ideal for busy multi-user facilities.
Additional information on the MFP-3D Infinity and its entire range of new capabilities, scan techniques, and accessories can be found at www.AsylumResearch.com/Infinity. To receive a quotation, email us at sales@AsylumResearch.com

SETSYS Evolution TG-DTA & TG-DSC under aggressive and corrosive atmospheres

INTRODUCTION

Working under corrosive atmospheres in a STA (TGA with DTA or DSC rod) with corrosive atmospheres is extremely challenging because the detectors are made from metallic parts. The different experiments where there is a risk of deterioration or corrosion is as followed:

  emission of aggressive vapours coming from the sample decomposition

  investigation in an oxidative or reducing gas

  investigation in corrosive gas

MATERIALS COMPATIBILITY

In the TG-DTA and TG-DSC modes, the detectors suspended to the balance are made of different metals according to the temperature range (platinel, platinum rhodium, tungsten rhenium …). The crucibles used with the different detectors are made in aluminium, platinum, tungsten, graphite (figure 1). Special crucibles in zirconia, boron nitride can also be adapted.

The materials compatibility for the TG-DTA and TG-DSC rods is very similar to the description done in Technical Note 679.  In the case of emission of agressive gas from the sample decomposition, each material has different limitations :

PLATINIUM, as a metal, is very sensitive to different types of gases and vapours.

  Metallic vapour

It is recommended to consider the corresponding phase diagram of Pt with the metal from the emitted vapour and check if there is a risk of eutectic formation. In case of low emission of vapour, one way to prevent direct contact between the crucible and the metallic vapour, is to have the sample embedded in alumina powder.
Another trick: with SiO2 work under air or oxygen to prevent the dissociation of the silicon oxide

  Hydrogen

Platinum is also very sensitive to hydrogen above 1000°C

  Other gases

Platinum is also stable in CO2. But it will react with CO, SO2, H2S, chlorine. In general, platinum is not recommended to be used in reducing atmospheres.

ALUMINA, as a ceramic oxide, is highly suited for applications at high temperature (up to 1750°C) under inert and oxidising but has some limitations in reducing atmospheres.

  Metallic vapour

It is recommended to consider the corresponding phase diagram of Pt with the metal from the emitted vapour and check if there is a risk of eutectic formation. In case of low emission of vapour, one way to prevent direct contact between the crucible and the metallic vapour, is to have the sample embedded in alumina powder.
Another trick: with SiO2 work under air or oxygen to prevent the dissociation of the silicon oxide.

  Hydrogen
At high temperature, a reduction of traces of oxides (especially SiO2) in alumina can be observed.

  Carboneous atmospheres (CO, CH4)
It is reported that the reduction of alumina with CH4 may occur from 1500°C

GRAPHITE is a very convenient material for DTA crucibles for applications at very high temperature (up to 2400°C) but only under inert atmosphere.

BORON NITRIDE is recommended for the investigation of molten metals when alumina cannot apply.

TUNGSTEN is also dedicated to applications at very high temperature (up to 2400°C) under inert atmosphere. It is used to build the DTA detector (combined with Rhenium) and the corresponding crucibles. Oxidative atmospheres have to be forbidden.

  Hydrogen
Tungsten is used in hydrogen atmosphere when platinum can not be used (above 1000°C).

SOLUTIONS TO WORK UNDER CORROSIVE CONDITIONS WITH TG-DTA MODE

Compared to the TG mode, the solutions to work under corrosive conditions with the TG-DTA and TG-DSCmodes are more limited. However here are some proposals to solve some problems in the TG-DTA.

Protected DTA rod (upper limit: 1750°C)

Making Raman spectroscopy made ‘quick and easy’

If you do Raman spectroscopy, you typically do it on a large and somewhat complex instrument. These systems provide high resolution results with full spectral coverage. But the high-end data comes with a high-end price tag for the research lab or organization, making Raman spectrometers less accessible to those with limited budgets or in teaching laboratories.

Bench-top Raman spectrometers offer an inexpensive alternative. They’re small, compact, ruggedized and portable while still delivering high sensitivity and repeatability. Most include auto-alignment so there’s no need to fiddle with lasers and optics. In other words, they’re a ‘quick and easy’ way to get quality measurements at a fraction of the price of higher-end systems.

These bench-top Raman instruments provide quality data at the push of a button. They can be configured with a variety of laser wavelengths, and are ideal for teaching the basics of Raman spectroscopy.

Outside of the classroom, they’re also useful when rapid quality measurements are a must, and complex instrumentation is not required. Bench-top Raman can be an affordable quality control tool for industries including food, pharmaceuticals and pulp & paper.

We are now partnered with BaySpec who offers a compact, light-weight Raman spectrometer with integrated laser and touch-screen computer. To learn more about the manufacturer and products related to this article, please visit the following link:
