TGA testing, or Thermo-Gravimetric Analysis, is an important method of material analysis. It mainly measures and analyzes the weight change of the material during heating to reveal the thermal stability and thermal decomposition behavior of the material.

In the TGA test, the sample is heated and gradually loses weight, a process that is precisely recorded. By analyzing the curve of weight with temperature, researchers can gain important information about the material's thermal stability and thermal decomposition behavior.
First, TGA tests can be used to study the thermal stability of materials. When the material is subjected to heat, its molecular structure may change, such as decomposition, oxidation or cross-linking. By observing how weight changes with temperature, researchers can learn at what temperature the material begins to lose weight and at what rate. This information is important for understanding the thermal stability and potential heat resistance of the material.
Second, the TGA test can also be used to study the thermal decomposition behavior of materials. When a material breaks down at high temperatures, its molecular structure changes and gases or volatile substances are released. By looking at how weight changes with temperature, researchers can learn at what temperature the material begins to break down, and at what rate. This information is important for understanding the thermal decomposition behavior of materials and their potential applications.
In addition, TGA testing can be used in combination with other analytical methods, such as DSC (Differential thermal analysis), to gain a more complete understanding of the thermal and chemical properties of materials.
In conclusion, TGA testing is a very important method of material analysis, which can provide important information about the thermal stability and thermal decomposition behavior of materials. This information is very important for understanding the properties and application prospects of materials, so it has been widely used in materials science, chemistry, biomedicine and other fields.
