Common special ceramic materials
According to different uses, special ceramic materials can be divided into structural ceramics and functional ceramics.
Alumina ceramics
The main composition of alumina ceramics is Al2O3. The company uses 996 alumina. Alumina ceramics have various excellent properties. High temperature resistance, generally long-term use at 1600 ℃, corrosion resistance, high strength and high wear resistance. It is widely used in ceramic substrates, structural ceramic parts, sealing rings, etc.
Silicon nitride ceramics
The main composition of silicon nitride ceramics is Si3N4, which is a high-temperature ceramic with high temperature strength, high hardness, wear resistance, corrosion resistance and self-lubrication. The linear expansion coefficient is the smallest among various ceramics, and the operating temperature is as high as 1400 ° C. Has excellent corrosion resistance, in addition to hydrofluoric acid, can withstand the corrosion of various other acids, and can withstand the corrosion of various metals, and has excellent electrical insulation and radiation resistance. Can be used as high-temperature bearings, seal rings used in corrosive media, thermowells, and metal cutting tools.
Silicon carbide ceramics
The main composition of silicon carbide ceramics is SiC. This is a high-strength, high-hardness, high-temperature-resistant ceramic. It can still maintain high bending strength when used at 1200 ° C to 1400 ° C. It is currently the highest temperature strength ceramic, silicon carbide ceramics. It also has good thermal conductivity, oxidation resistance, electrical conductivity and high impact toughness. It is a good high-temperature structural material, which can be used for parts that work at high temperatures such as rocket nozzle nozzles, thermocouple sleeves, furnace tubes, etc .; use its thermal conductivity to make heat exchanger materials at high temperatures; and use its high hardness and Abrasion resistance for making wheels, abrasives, etc.
Zirconia ceramics
Zirconia ceramics are widely used in the field of structural ceramics because they have the advantages of high toughness, high bending strength and high abrasion resistance, excellent thermal insulation properties, and thermal expansion coefficient close to that of steel.
Zirconia toughened alumina ceramic (ZTA)
Zirconia toughened alumina ceramic (ZTA) material: with high hardness, strength, fracture toughness and corrosion resistance, it can meet the requirements for use under service conditions. At the same time, in the manufacturing process, it can adapt to technological requirements such as forming, sintering, and processing. Gel injection molding technology has the characteristics of high density, uniform body, high strength, and quasi-net size molding.
