Thermoanalytical techniques can be used to characterize a wide range of inorganic materials and processes concerning them. The topics covered involve the measurement of thermal properties, phase equilibria, chemical analysis, and the study of solid-state reactivity. Examples are selected to include applications to metals, ceramics, minerals and a variety of inorganic compounds. Applications to processes such as catalysis, crystal growth, and synthesis are described.

The principle techniques chosen for these purposes are associated with the measurement of different properties as a function of temperature and time. Thermogravimetry (TG), thermomagnetometry (TM), and evolved gas analysis (EGA) are based on changes in weight and analysis of the materials evolved or consumed. Differential thermal analysis (DTA) and differential scanning calorimetry (DSC) are concerned with changes in temperature and heat capacity. Thermodilatometry (TD) measures changes in length or volume. Examples illustrating the use of each of these techniques are described.
