Thermal Analysis is a scientific technique used to study the properties of materials as they change with temperature. It involves measuring physical and chemical changes in a substance when it is heated or cooled. Common methods include Differential Scanning Calorimetry (DSC) and Thermogravimetric Analysis (TGA), which help identify phase transitions, thermal stability, and composition. This analysis is crucial in various fields, including materials science, chemistry, and pharmaceuticals. By understanding how materials respond to temperature changes, researchers can improve product performance, ensure safety, and develop new materials with desired properties.
