Thermal Analysis

Thermal analysis is a branch of materials science where the properties of materials are studied as they change with temperature. Several methods are commonly used – these are distinguished from one another by the property which is measured.The interaction of a material and heat are measured by Calorimetry and thermogravimetric analysis.It is used to control the temperature in a predetermined way - either by a continuous increase or decrease in temperature at a constant rate either by linear heating/cooling or by carrying out a series of determinations at different temperatures in a stepwise isothermal measurements. More advanced temperature profiles have been developed which use an oscillating which are usually sine or square wave of heating rate which is Modulated Temperature Thermal Analysis or modify the heating rate in response to changes in the system's properties by Sample Controlled Thermal Analysis.
