Thermal Analysis

Thermal analysis obtained by determining the coefficient of linear thermal expansion, consists of dimensional increase or shrinkage through the action of heat. This experiment is a consequence of the increase of its internal energy, where it determines a greater amplitude of molecular thermal vibrations among its structural constituents.

Quartz is the most frequent accessory substance in ceramic materials. When the quartz is heated, there is a great dilation which is attributed to the transformations in the crystalline chains. The bigger the thermal expansion in the temperature range of 500°C to 600 ° C, the more quartz is present, and the earlier the rise, the finer the corresponding quartz grains are.
