Dilatometry is a thermo analytical technique, which measures linear dilation (expansion/shrinkage) of solid materials as a function of temperature. By measuring the linear dilation of a material as a function of temperature (or time), its physico-chemical characterization can be carried out, which include evaluation of coefficient of thermal expansion, sintering behavior, glass transition and other structural phase transitions, etc. The technique is also used to study solid-gas surface chemical reactions under controlled conditions. The technique finds wide application in study and development of a variety of materials (ceramics, polymers, metals, alloys, glasses, composites, etc.) in research, development, quality control and engineering applications.

SALIENT FEATURES OF DEVELOPED EQUIPMENT
