What is Differential Thermal Analysis (DTA)?
A thermal analysis technique that measures the temperature difference between a sample and a reference material as both are heated or cooled at the same rate. DTA detects thermal events like phase transitions, decompositions, and chemical reactions.

Frequently Asked Questions
A thermal analysis technique that measures the temperature difference between a sample and a reference material as both are heated or cooled at the same rate. DTA detects thermal events like phase transitions, decompositions, and chemical reactions.
DTA is used in ceramics (sintering studies), mineralogy (clay mineral identification), metallurgy (alloy phase diagram determination), and explosive material characterisation. It is simpler and less expensive than DSC but less quantitative.
DTA of unknown materials can detect exothermic decomposition events, providing critical process safety data. DTA/DSC screening of new chemical entities before scale-up is a standard safety practice in the chemical industry.
The formula or notation for Differential Thermal Analysis (DTA) is: ΔT = T_sample − T_reference
