Differential Thermal Analysis (DTA)

Differential Thermal Analysis (DTA) is a technique used to study how a material's temperature changes when heated or cooled. It measures the difference in temperature between a sample and a reference material as they are subjected to the same temperature program. When the sample undergoes a physical or chemical change—such as melting, crystallizing, or reacting—this causes a characteristic temperature difference. These changes show up as peaks or dips on a DTA curve, helping scientists identify and understand the thermal properties and behaviors of materials with precise detail.
