Thermal alteration is a research area that focuses on studying the changes in composition, structure, and properties of materials when exposed to high temperatures. This process can occur in various environments such as combustion, pyrolysis, or thermal oxidation. The goal of thermal alteration research is to understand how materials behave under extreme heat conditions and to develop strategies for controlling and optimizing these processes for various applications such as manufacturing, energy production, and waste management. Study of thermal alteration can involve various techniques such as thermogravimetric analysis, differential scanning calorimetry, and Fourier-transform infrared spectroscopy.
