Energy-containing materials

Thermogravimetric Analysis (TGA)

TGA technology measures the mass change of samples under programmed temperatures to study the thermal stability, decomposition temperature, and component content of energetic materials. For instance, TGA can determine the initial decomposition temperature, maximum weight loss temperature, and reaction completion temperature of energetic materials, which are crucial for evaluating the thermal stability and service life of the material. Additionally, TGA can be combined with other analytical techniques, such as infrared spectroscopy and mass spectrometry, to further investigate the composition of evolved gases at different temperatures.

Differential Scanning Calorimetry (DSC)

DSC technology measures the heat difference between the sample and reference material as the temperature changes, enabling the study of the thermal effects and phase transition processes of energetic materials. For instance, DSC can determine the melting and crystallization temperatures, as well as thermal effects of energetic materials, which is highly useful for evaluating the purity and thermal properties of the materials.

Thermodecomposition Kinetics Research

Through thermal gravimetric analysis, the thermal decomposition kinetics of energetic materials can be studied, determining their activation energy and reaction rate constants. This aids in optimizing material formulations and process conditions, enhancing material performance and stability.

Composition Analysis

TGA and DSC can be combined with other analytical techniques for qualitative and quantitative analysis. For instance, using TGA-FTIR technology, the content of carbon black or inorganic fillers in energetic materials can be analyzed both qualitatively and quantitatively. This method is of great significance in the formulation design and quality control of energetic materials.

‌Application Fields‌

Thermal analysis techniques are extensively applied in the field of energetic materials, including explosives, propellants, and gunpowder. Through thermal analysis, one can study the thermal stability, decomposition characteristics, and combustion properties of these materials, providing crucial basis for material design and improvement.
