Qualification Certificate
Due to its excellent wear resistance, corrosion resistance, high temperature resistance, low density and other properties, ceramic materials are recognized as one of the vibrant new materials in the 21st century. It is listed as the four contemporary engineering materials alongside metal materials, polymer materials, and composite materials.
| Silicon Nitride Ceramics (Si3N4) | Alumina Ceramics (Al2O3) | Silicon Carbide Ceramic (SiC) |
| Silicon nitride exceeds other ceramics in thermal shock resistance. Its strength does not deteriorate at elevated temperatures, hence it is most appropriate for engine and gas turbine parts, including turbo charger rotors, diesel engine glow plugs and hot plugs. | Alumina is the most widely used type of ceramic. Its high dielectric properties are beneficial in electrical products, Alumina offers corrosion and wear resistance and high strength. It is widely used for industrial machine parts. | Silicon carbide retains its strength at elevated temperatures as high as 1400ºC. It has the highest corrosion resistance of all fine ceramic materials. Applications include mechanical seals and pump parts. |
| Zirconia Ceramics (ZrO2) | Aluminum Nitride Ceramics(AIN) | Machinable Glass Ceramic |
| Zirconia ceramic has the highest strength and toughness at room temperature of all engineering ceramics. Before zirconia, ceramics were considered impractical for scissor or knife applications. With its excellent surface smoothness, zirconia is also used for pump parts. | Aluminum nitride ceramics are usually gray or off-white. It has a low thermal expansion coefficient, excellent insulation performance, heat resistance, and a thermal conductivity of more than 180W/(m.k). It is an ideal package heat dissipation material for large integrated circuits. | Machinable glass ceramics are fluorophlogopite mica glass ceramics with synthetic mica as the main crystal phase. The main components are fluorophlogopite and glass with silica as the main component. Contains 55% fluorophlogopite and 45% borosilicate glass matrix. |
| Microporous Ceramic Plate | Boron Nitride(h-BN) | Other Ceramics |
| Microporous ceramics refer to ceramic bodies containing a large number of open or closed tiny pores. The material is mainly alumina or carbonized. The surface is firm, the pores are uniform, the porosity is 35-40%, and the pore size ranges from 1 to 100 microns. | Boron nitride material has the characteristics of resistance to high temperature and heat cycle. It will not react with many metals, ceramic rare earths and other materials, nor will it contaminate the product. Will not break in hot and cold environments. | Our company can process a variety of ceramic materials and cemented carbide. We are currently processing experimental splines for many research institutes and schools. You can provide materials and we can process them according to drawings. |
