Refractory materials application of electron microscope
Since the chemical composition, mineral composition and microstructure of refractory materials determine the properties of refractory materials; newer analysis methods for the chemical composition of refractory materials include colorimetry, organic reagent (complex) titration, flame photometry, and spectral analysis method, X-ray fluorescence analysis method, etc.; and polarizing microscopes and scanning electron microscopes are the most effective means to analyze the mineral composition and microstructure of refractory materials, so high-quality polarizing microscopes and scanning electron microscopes are currently produced and produced by refractory material companies. Indispensable equipment for testing, evaluating and guiding production processes in research and development.
The specific applications of polarizing microscopes and scanning electron microscopes in refractory materials are:
1. Use polarizing microscopes and scanning electron microscopes to analyze the mineral composition and microstructure of refractory materials. The properties of refractory materials mainly include chemical-mineral composition, organizational structure, mechanical properties, thermal properties and high-temperature use properties. Refractory materials are heterogeneous bodies composed of solid phase (including crystal phase and glass phase) and pores. Their relative quantity, distribution and combination form constitute the microstructure of refractory materials. The physical and chemical properties of refractory materials are determined by the crystal phase of the refractory materials. The crystal phase structure is determined by the production process and ingredient minerals of refractory materials. Microscopes and scanning electron microscopes are mainly used to analyze the crystalline phase structure and gas phase structure of refractory materials, thereby guiding the production process of refractory materials and the addition ratio of ingredient minerals, etc., and ultimately achieving the physical and chemical property requirements of refractory materials and meeting the application of refractory materials. performance.
2. Use polarizing microscopes and scanning electron microscopes to evaluate and analyze the refractory resistance, thermal shock stability, porosity distribution, and slag corrosion resistance of refractory products, thereby improving the quality of refractory products and meeting the current market requirements for a new generation of advanced refractory products. Material quality requirements.
