        Special ceramics is one of the key areas of my country's high-tech industry. my country's electronic information, automobiles, chemicals, building materials, light industry and national defense construction all have a huge demand for special ceramics, and the market prospect is very broad. It is estimated that in 2010, my country's special ceramic industry will achieve an output value of 30 billion yuan. In the future, my country will pay more attention to the practical application development and market cultivation of special ceramics, and focus on the organic combination of high performance and low cost.

          

        According to different properties, special ceramics can be divided into structural ceramics and functional ceramics. Structural ceramics are also called engineering ceramics. They are ceramic materials that mainly use the mechanical properties of ceramics such as strength, stiffness, willfulness, wear resistance, hardness, and fatigue strength. There are high strength ceramics, (ultra) high temperature ceramics, (ultra) low temperature ceramics, high toughness ceramics, super hard ceramics and nano ceramic lamps. Functional ceramics are mainly ceramic materials that use the electrical, magnetic, optical, acoustic, thermal, and lamp properties of ceramics and their coupling effects. The main types are electronic ceramics, sensitive ceramics, optical ceramics, bioceramics, magnetic ceramics and superconducting ceramics. About 60% of functional ceramics are electronic ceramics, which include ferroelectric ceramics, piezoelectric ceramics, semiconductor ceramics, and dielectric ceramics.

     

       my country attaches great importance to the development and application of special ceramics. It started early, invested a lot, and involved many parts. In terms of the types of special ceramics, my country has carried out research, development and production of almost all special ceramic materials, and has formed a relatively complete research and development system. In recent years, China has made special ceramics a key point in the development of high-tech industries. During the "Seventh Five-Year Plan" and "Eighth Five-Year Plan" period, China has invested 100 million yuan in the development of special ceramics, including research funding for automotive ceramic engines. Up to 30 million yuan.

 

       Special ceramics in China started in the 1950s and 1970s to support the "two bombs and one satellite", mainly for the development of high-temperature and ablation-resistant special ceramic materials for nuclear testing and aerospace. The focus of leisure applications has shifted to Mainly for civilian use. The huge market demand for special ceramics in China provides great opportunities for the development of the special ceramic industry.

     

       At present, my country's special ceramics industry is concentrated in Beijing, Shanghai, Tianjin, Jiangsu, Shandong, Zhejiang, Fujian, Guangdong and other coastal cities and regions. Some urban areas in central China such as Wuhan, and remote areas such as southwest and northwest are dominated by the original third-tier military enterprises, and electronic ceramics are mostly concentrated in Beijing and Guangdong. Fujian and the Yangtze River Delta, etc.
