Thermal analysis is a general term that describes the technique used to analyze the time and temperature at which physical changes occur when a substance is heated or cooled.
Thermal analysis methods is widely used in the analysis of materials such as clay,ceramic, polymers, salt mixtures, mineral salts, alloys, metals, pharmaceuticals, and in the field of quality control.
In analysis methods, each technique is defined according to the types of physical changes analyzed.
The most common thermal analysis techniques are differential scanning calorimetry (DSC), thermogravimetric analysis (DTG), thermomechanical analysis (TMA), and derivative thermogravimetric analysis (TGA).
- DSC is a thermal analysis technique that measures the temperature and heat flow between sample and reference sample associated with material transitions as a function of time and temperature.
- TGA detects the temperature at which a material loses weight or does not lose weight. It creates the rate of change in weight as a function of time or temperature.
- The purpose of DTG analysis is to see the temperature at which the material loss is the most. Accordingly, it creates a function of time or temperature versus the speed of the weight loss of the material.
- TMA are measurements based on size and viscosity changes. These methods also offer precise and fast solutions in the structure analysis of substances and impurity control.
