With the rise of electronic technology, space technology, laser technology, computer technology and other new technologies, as well as the development of basic theory and testing technology, ceramic materials research by leaps and bounds, in order to meet the special performance requirements of new technology for ceramic materials, and traditional ceramics have a very different class of ceramics -- special ceramics came into being. Some experts predict that the fierce competition of daily ceramics and building sanitary ceramics will certainly develop into a worldwide fierce competition of special ceramics in the near future. The development prospect of special ceramics is broad. Then, what kind of development process has special ceramics experienced? What is the status quo? Where is the future headed? Shenzhen Fangtai New Materials has customized high-end micro-porous Ceramic vacuum suckers, porous ceramics, Ceramic chuck, and adsorbs silicon wafers, wafers, ceramic wafers, flexible screens, glass screens, circuit boards and various non-metallic materials.

 

Development history of special ceramics: It is generally believed that special ceramics are a class of ceramics with high performance, which adopt highly selected or synthetic raw materials, can accurately control the chemical composition, and is processed according to the manufacturing technology that is convenient for the design and control of microstructure. According to their characteristics and uses, special ceramics can be roughly divided into structural ceramics and functional ceramics. Structural ceramics with high strength, high hardness, high elastic modulus, high temperature resistance, wear resistance, corrosion resistance, oxidation resistance, thermal shock resistance and other characteristics, can be used as engineering structural materials. Functional ceramics have electrical, magnetic, optical, acoustic, superconducting, chemical, biological and other properties, and have the function of mutual conversion, can be roughly divided into electronic ceramics, transparent ceramics, biological and antibacterial ceramics, optical, luminescent and infrared radiation ceramics, porous ceramics.

 

Relevant data show that China has been studying special ceramics since the 1950s, mainly made of alumina ceramics. In the 1960s, to meet the needs of the development of electronic technology and nuclear technology, the research and development of special ceramics have been gradually developed. Beryllium oxide, calcium oxide and other non-oxide special ceramics have come into being. During the Seventh and Eighth Five-Year Plan period, the development and application of Chinese special ceramics have entered a new stage. Up to now, there have been more than 300 universities, research institutes and production enterprises engaged in the development and development of special ceramics. The units engaged in functional ceramics accounted for 63.6 percent, and those engaged in structural ceramics accounted for 36.4 percent, mainly distributed in cities in coastal areas of Jiangsu, Zhejiang, Shanghai, Shandong, Tianjin, Beijing, Fujian and Guangdong. In the remote areas of southwest and northwest China, the units engaged in the development of special ceramics are mainly former military enterprises. Around 1976, Tsinghua University successfully developed a hot pressing method to produce silicon nitride toughened alumina tool. Jiangsu Ceramic Research Institute has been committed to the research and development and mass production of special ceramics since the early 1980s. It has successfully developed PTC series of textile porcelain parts, ceramic friction plates, piezoelectric ceramics, foam ceramics, electric vacuum tubes and ceramic filter plates, etc., which have made positive contributions to the development of Chinese special ceramics. In 1991, Foshan Ceramic Institute of Guangdong took the lead in establishing the first production line with an annual output of 100,000 ceramic rollers in China, which strongly promoted the vigorous development of architectural ceramics. The "New oxygen sensor for Car Engine Electronic Control Injection System", "Al2O3 crystal drawing rod" and "piezoelectric ceramic micro-compensation plate" developed by Tianjin University have also been successful. Among them, "Oxygen sensor for car engine electronically controlled injection System" is a key project of national "863", and has formed an annual production capacity of 30,000 pieces. "Piezoelectric ceramic micro-displacement compensation plate" is a national defense engineering supporting project. "Al2O3 crystallization rod" filled the gap in this field in China. Motorcycles produced in Taiwan are gradually entering the era of ceramic cylinder, and are ready to enter the developed markets such as Europe and the United States.
