Infrared emission spectroscopy is a novel technique, which allows the spectra of inorganic materials to be obtained in situ at elevated temperatures. The hot sample becomes the source. High quality spectra with good signal to noise ratio may be obtained using thin films or films of micronised powders. Sets of spectra from 100 to 800 ° C and higher at an appropriate temperature intervals may be obtained. These spectra enable thermal transformation phenomena such as dehydration, dehydroxylation and phase changes together with changes in molecular structure to be studied. Application of the IES technique to naturally occurring minerals, synthetic minerals, and inorganic materials are shown. Advantages and disadvantages of the technique are discussed.
