MECHANICAL&INDUSTRIAL CERAMICS


Due to its excellent wear resistance, corrosion resistance, high temperature resistance, low density and other properties, ceramic materials are recognized as one of the vibrant new materials in the 21st century. It is listed as the four contemporary engineering materials alongside metal materials, polymer materials, and composite materials.
According to performance and use, ceramic materials are divided into traditional ceramics and advanced ceramics. Advanced ceramics and traditional ceramics are significantly different in terms of raw materials, structure, and preparation techniques. The performance of the two is also very different. Advanced ceramic materials far surpass modern high-quality alloys and polymer materials in certain properties. Therefore, it has a wide range of application value and potential in various industrial fields, such as petroleum, chemical, steel, electronics, textile and automobile industries, as well as cutting-edge technology fields such as aerospace, nuclear industry and military industry.
