  2. Thermogravimetric analysis - Wikipedia

    en.wikipedia.org/wiki/Thermogravimetric_analysis

    Thermogravimetric analysis or thermal gravimetric analysis (TGA) is a method of thermal analysis in which the mass of a sample is measured over time as the temperature changes. . This measurement provides information about physical phenomena, such as phase transitions, absorption, adsorption and desorption; as well as chemical phenomena including chemisorptions, thermal decomposition, and ...

  3. Tammann and Hüttig temperatures - Wikipedia

    en.wikipedia.org/wiki/Tammann_and_Hüttig...

    The Tammann temperature is important for reactive compounds like explosives and fuel oxiders, such as potassium chlorate (KClO 3, T Tammann = 42 °C), potassium nitrate (KNO 3, T Tammann = 31 °C), and sodium nitrate (NaNO 3, T Tammann = 17 °C), which may unexpectedly react at much lower temperatures than their melting or decomposition ...

  4. Thermal analysis - Wikipedia

    en.wikipedia.org/wiki/Thermal_analysis

    Polymers represent another large area in which thermal analysis finds strong applications. Thermoplastic polymers are commonly found in everyday packaging and household items, but for the analysis of the raw materials, effects of the many additive used (including stabilisers and colours) and fine-tuning of the moulding or extrusion processing used can be achieved by using differential scanning ...

  5. Thermal decomposition - Wikipedia

    en.wikipedia.org/wiki/Thermal_decomposition

    Another example of thermal decomposition is 2Pb(NO 3) 2 → 2PbO + O 2 + 4NO 2. Some oxides, especially of weakly electropositive metals decompose when heated to high enough temperature. A classical example is the decomposition of mercuric oxide to give oxygen and mercury metal.

  6. Pyrolysis - Wikipedia

    en.wikipedia.org/wiki/Pyrolysis

    Pyrolysis generally consists in heating the material above its decomposition temperature, breaking chemical bonds in its molecules. The fragments usually become smaller molecules, but may combine to produce residues with larger molecular mass, even amorphous covalent solids .

  7. Differential thermal analysis - Wikipedia

    en.wikipedia.org/wiki/Differential_thermal_analysis

    Differential thermal analysis (DTA) is a thermoanalytic technique that is similar to differential scanning calorimetry.In DTA, the material under study and an inert reference are made to undergo identical thermal cycles, (i.e., same cooling or heating programme) while recording any temperature difference between sample and reference. [1]

  8. Evolved gas analysis - Wikipedia

    en.wikipedia.org/wiki/Evolved_gas_analysis

    Evolved gas analysis (EGA) is a method used to study the gas evolved from a heated sample that undergoes decomposition or desorption.It is either possible just to detect evolved gases using evolved gas detection (EGD) or to analyse explicitly which gases evolved using evolved gas analysis (EGA). [1]

  9. Differential scanning calorimetry - Wikipedia

    en.wikipedia.org/wiki/Differential_scanning...

    DSC can also be used to study thermal degradation of polymers using an approach such as Oxidative Onset Temperature/Time (OOT); however, the user risks contamination of the DSC cell, which can be problematic. Thermogravimetric Analysis (TGA) may be more useful for decomposition behavior
