differential thermal analysis
"Differential thermal analysis" (DTA) is a key technique in studying the thermal properties and phase transitions of materials by comparing their temperature changes to a reference.

Definition
C1Analytical Chemistry
(technical, scientific)A technique measuring the temperature difference between a sample and an inert reference material during identical thermal cycles.
Example
- Using differential thermal analysis, the scientist observed the melting point of the compound.
C1Materials Science
(technical, scientific)A method to detect thermal transitions like phase changes by comparing the temperatures of a sample and a reference material during heating or cooling.
Example
- Differential thermal analysis helped identify the crystallization temperature of the new alloy.
C1Physical Chemistry
(technical, scientific)A process that records temperature differences between a sample and a reference to study thermal events such as melting and sublimation.
Example
- The differential thermal analysis curve indicated an exothermic reaction occurring in the sample.
