Differential Thermal Analysis

Differential Thermal Analysis (DTA) detects the release or absorption of heat, which is associated with chemical and physical changes in materials as they are heated or cooled and this information is essential for understanding the thermal properties of materials.

Analysis of decomposition of glass batch materials, crystalline phase changes, chemical reactions and glass transition temperature are some of the properties measured with DTA. The temperature range of the instrument is from ambient to 1000º C. 

A typical DTA trace identifies  the glass transition temperature (T g ) , the bulk crystallisation (T b ) , the liquidus temperature (T l ) , and minor crystalline phases and other features occurring as other peaks or troughs. An example trace is shown above.

This method can give more detailed information on some of these properties than other techniques such as dilatometry.
