High-Temperature Advanced Ceramics: A Key Support for the Preparation of High-End Precious Metals
High-end manufacturing industries such as semiconductors, new energy, and precision electronics have a huge demand for precious metals. Precious metals possess excellent electrical conductivity, corrosion resistance, high-temperature stability, and catalytic properties, leading to a surge in market demand. The preparation of precious metals involves complex processes, including purification, high-temperature smelting, vacuum treatment, atmosphere sintering, powder metallurgy, crystal growth, and precision machining. Because precious metals have extremely high melting points and strict low-impurity requirements, the internal components of production equipment must offer excellent thermal stability, high purity, thermal shock resistance, and corrosion resistance. Traditional metal materials are prone to oxidation, deformation, or contamination in extreme high-temperature environments. Advanced ceramics overcome these limitations and have become core materials in preci...
