DIFFERENTIAL THERMAL ANALYTICS
DIFFERENTIAL THERMAL ANALYTICS It is a thermal analytic technique that can be used as a fingerprint for the identification of different materials like clays, minerals, cement, etc. DTA allows the detection of every chemical and physical change whether or not it is accompanied y a change in weight. In DTA, the temperature of the samples and a thermally inert reference material are measured as a function of temperature. The differential temperature (∆T) vs the programmed temperature (T) gives the temperature at which the transition occurs and whether the transition is exothermic or endothermic.
