Products made of new industrial special ceramic materials are widely used as engineering structural materials and functional materials in: petroleum machinery, textile electronics, chemical smelting, instrumentation, photovoltaic energy , food and medical, laser semiconductor, automotive and military industry, aerospace and other high-end fields. The most commonly used ones are: Zirconium dioxide (ZrO2) and Alumina (Al2O3).
Industrial new special ceramics are also called fine ceramics. According to their application functions, they can be roughly divided into two categories: high strength, high temperature resistance and composite structure ceramics and electrical and electronic functional ceramics. . Specially formulated inorganic materials are added to the ceramic blank and sintered at a high temperature of about 1360 degrees to obtain stable and reliable anti-static properties. It becomes a new type of special ceramic, which usually has one or more functions, such as: electrical, magnetic, Light, heat, sound, chemistry, biology and other functions; and coupling functions, such as piezoelectric, thermoelectric, electro-optical, acousto-optical, magneto-optical and other functions.
Data show that the different chemical compositions and organizational structures of special ceramics determine their different special properties and functions! Due to their special properties, some economically developed countries, especially Japan, the United States and Western European countries, have invested a lot of manpower, material and financial resources in the research and development of special ceramics in order to accelerate the new technological revolution and lay a material foundation for the development of new industries. Therefore, the development of special ceramics Very fast and a great breakthrough in technology. Special ceramics play an increasingly important role in modern industrial technology, especially in high-tech and new technology fields. The international market size of special ceramics is expected to reach 50 billion US dollars at the beginning of this century. Therefore, many scientists predict that special ceramics will surely occupy a very important position in the development of science and technology in the 21st century.
