Description
Advanced technical ceramics have the advantages of metal and other materials that do not have. With the development of science and technology, especially the development of energy and space technology, materials need to be used in relatively harsh conditions. The development of space technology (such as spacecraft nozzles, combustion chamber linings, jet engine blades, etc.) puts forward higher and higher requirements for materials. Reactors, heat exchangers, and nuclear fuels in petrochemicals, energy development, etc. require materials with high temperature resistance, corrosion resistance, and wear resistance to become increasingly stringent. It can be seen that advanced ceramics are becoming more and more important, and the demand for its varieties is increasing day by day.

Applications
Products made of industrial ceramics have a wide range of uses. With its high mechanical strength and high insulation resistance, it can be used as vacuum devices, device porcelain, thick film and thin film circuit substrates, thyristor and solid circuit shells, spark plug insulators, etc. With its high strength and hardness, it can be used as abrasives, textile ceramics, knives, etc. With its chemically stable and better performance, it can be used as chemical and biological ceramics, artificial joints, replacement of platinum crucibles, catalytic carriers, and aviation and magnetic fluid power generation materials. With the development of science and technology and the improvement of manufacturing technology, new varieties of high temperature engineering ceramics continue to appear, which will be more and more widely used in modern industry and modern science.
