Super ceramics can be divided into iron oxide ceramics, alumina ceramics, titanium oxide ceramics, silicon oxide ceramics, silicon carbide ceramics, and cermets according to the composition of raw materials.
The application range of special ceramics has expanded from capacitors, filters, igniters, thermal insulation materials, medical equipment and communication components to high-tech fields such as aerospace, satellites and semiconductor chips.
The research and production of special ceramics in China have developed a lot in the past 20 years, but they are still far from developed countries in terms of practical application, production level and industrialization.
At present, foreign special ceramics can be divided into iron oxide ceramics, alumina ceramics, titanium oxide ceramics, silicon oxide ceramics, silicon carbide ceramics, and cermets according to the composition of raw materials.
The application range of special ceramics has expanded from capacitors, filters, igniters, thermal insulation materials, medical equipment and communication components to high-tech fields such as aerospace, satellites and semiconductor chips.
According to forecasts, the world's special ceramics have been growing at a rate of 15% to 20% since 2000, and sales in 2010 are expected to reach about 150 billion US dollars.
In recent years, the Chinese Academy of Sciences has developed new nano-ceramics, and found that the strange properties of nano-metals-superplastic ductility, nano-copper can be extended 50 times at room temperature continuously.
At the same time, national nano-materials, nano-calcium carbonate, silicon-based nano-ceramic powder and products are included in the special announcement of high-tech industrialization organized by the state.
China has successfully adopted various methods to make ceramic particle materials, including zirconia, titanium oxide, aluminum oxide, silicon oxide, silicon carbide, and silicon nitride.
In order to expand the application of nano-particle materials in ceramic modification, scientists have proposed the use of nano-addition technology to promote the comprehensive improvement of conventional ceramics. This indicates that the development of special ceramics has entered a new "world". The industry will make a new leap.
What ceramic materials are good for medical devices? Super ceramic, one of the special ceramics, is definitely the best ceramic material!
