Applications Of Termogravimetric Analysis:
In the earlier section we have seen how TGA could be used to understand the chemistry of decomposition of a particular compound. TGA also gives information about the temperature range over that a particular sample appears to be stable or unstable. We have also interpreted TG curves qualitatively. Beside these there are several other applications of thermogravimetric analysis. A few are listed below:
i) Purity and thermal stability.
ii) Solid state reactions.
iii) Decomposition of inorganic and organic compounds.
iv) Determining composition of the mixture.
v) Corrosion of metals in various atmosphere.
vi) Pyrolysis of coal, wood and petroleum.
vii) Roasting and calcinations of minerals.
viii) Reaction kinetics studies.
ix) Evaluation of gravimetric precipitates.
x) Oxidative and reductive stability.
xi) Determining moisture, ash contents and volatile.
xii) Desolvation, desorption, vaporizations, sublimation, sorption, chemisorptions.
It is not probable to discuss all these applications at this level; it is worth to define some of the applications that are more general.
