STA: The Combination of DSC und TGA Measurements
The combination of Dynamic Scanning Calorimetry (DSC) and Thermogravimetry (TGA) provides comprehensive information about the melting behavior, solid-solid transitions or compositional analysis of high-temperature materials, such as glass, ceramics, metals and high temperature composites. Moreover, by performing these measurements under different gas atmospheres like oxidizing, reducing, inert or humid atmosphere, it is possible to gain a deeper understanding of reactivities and the effects of the atmosphere on the sample. For instance, the reactions of a material with oxygen or water vapor can be studied, providing insight into its oxidation behavior. This information is crucial in understanding high-temperature materials and developing new materials with improved properties.
Additional Information about Gases Evolved
But that's not all – NETZSCH lab also offers the optional possibility of hyphenation between STA and Evolved Gas Analysis (EGA). With this added capability, we can analyze the gases evolved during thermal analysis processes to identify the chemical composition of the materials being tested. This provides even more detailed information on the material characteristics, such as their decomposition pathways and reaction mechanisms. NETZSCH offers couplings to gas analyzers like infrared spectrometers (FT-IR), mass spectrometers (MS) or gas chromatography mass spectrometers (GC-MS).
For example, you are a manufacturer of ceramic tiles, and you need to ensure that your tiles can withstand high temperatures without cracking or breaking. NETZSCH STA service can analyze a sample of your ceramic material by subjecting it to a controlled heating and measure its mass change and heat flow. NETZSCH characterizes, for example, the debinding profile of your ceramic green body and determine the specific heat capacity of your fired ceramic part.
