Introduction
SiC ceramics not only have excellent mechanical properties at room temperature, such as high bending strength, excellent oxidation resistance, good corrosion resistance, high wear resistance and low friction coefficient, but also high temperature mechanical properties (strength, creep resistance, etc.) are the best known ceramic materials.
Hot pressing sintering, non-pressing sintering, hot isostatic pressing sintering materials, its high temperature strength can be maintained to 1600℃, is the best high temperature strength of ceramic materials. The oxidation resistance is also the best of all non-oxide ceramics. Another name for emery. SiC ceramics have been widely used in petroleum, chemical industry, microelectronics, automobile, aerospace, aviation, paper making, laser, mining and atomic energy.
Silicon carbide has been the most widely used material for the use of structural ceramics.
Characteristics such as relatively low thermal expansion, high force-to-weight radius, high thermal conductivity, hardness, resistance to abrasion and corrosion, and most importantly, the maintenance of elastic resistance at temperatures up to 1650 ° C, have led to a wide range of uses.
Silicon carbide ceramic parts is an inorganic non-metallic material, because of its high hardness, high wear resistance, high corrosion resistance and high temperature strength, it is used in a variety of mechanical parts requiring wear resistance,corrosion resistance and high temperature resistance.
Silicon carbide ceramic features:
1. Better wear resistance
2. Better corrosion resistance
3. Excellent oxidation resistance
4. High heat conductivity and good heat conduction effect
5. The strength remains unchanged in high temperature environment
6. High heat conductivity and good heat conduction effect
