The different chemical composition and structure of special ceramics determine its different special properties and functions. Such as high strength, high hardness, high toughness, corrosion resistance, conductivity, insulation, magnetic, light transmission, semiconductor and piezoelectric, optoelectronic, electro-optical, acousto-optic, magneto-optical and so on. Because of special performance. Such ceramics can be used as engineering structural materials and functional materials in machinery, electronics, chemical engineering, smelting, energy, medicine, lasers, nuclear reactions, aerospace, etc.
Some economically developed countries, especially Japan, the United States, and Western European countries, in order to accelerate the new technological revolution, lay a material foundation for the development of new industries, invest a lot of manpower, material and financial resources to research and develop special ceramics, so the development of special ceramics is very rapid. There are also major breakthroughs in technology. Special ceramics have become increasingly important in modern industrial technology, especially in the fields of high technology and new technology.
At the beginning of this century, the international market size of special ceramics is expected to reach 50 billion U.S. dollars, so many scientists predict that special ceramics will certainly occupy a very important position in the development of science and technology in the 21st century.
