Fine Powder Silicon Carbide

Fine powder silicon carbide, also known as carborundum, is a hard chemical compound containing silicon and carbon. They are widely used for abrasives, refractory, metallurgy, and SiC wafer, etc. Grains of silicon carbide can be bonded together by sintering to form very hard ceramics that are widely used in applications requiring high endurance, such as car brakes, car clutches and ceramic plates in bulletproof vests.

Description

Problems with silicon carbide materials

Silicon carbide has high hardness and brittleness, and is difficult to process into complex shapes, which restricts its application in
some areas of application. Since the surface of silicon carbide easily reacts with oxygen and is easily oxidized at high temperatures, its performance decreases, reducing the stability and wear resistance of the material. Silicon carbide material has high hardness and brittleness, and is prone to cracks and fractures when subjected to stress. Affects its service life and reliability. Silicon carbide has a high thermal conductivity and expands significantly at high temperatures, which can easily cause thermal stress. The force causes material deformation, cracking and other problems.

The surface of silicon carbide materials is treated with oxide or metal film to prevent the entry of oxygen and water vapor and reduce the oxidation rate of the material. Silicon carbide materials are reinforced by organic alloys, fiber reinforcement and other methods to improve the fracture toughness and crack resistance of the materials and reduce the risk of fracture. Through reasonable heat treatment processes, the internal stress of silicon carbide materials is reduced, the impact of thermal stress on the materials is reduced, and cracking caused by thermal expansion is avoided. Advanced processing technology and equipment, such as laser processing and ultrasonic processing, are used to achieve high-precision processing of silicon carbide materials and improve processing quality and efficiency.
