Characteristics of silicon carbide

Time:2024-3-12 11:26:57 
Silicon carbide is a new type of inorganic non-metallic material with many excellent properties, widely used in fields such as electronics, optoelectronics, chemical engineering, metallurgy, etc.Its main characteristics are as follows:
1: High hardness
Silicon carbide has extremely high hardness, with a Mohs hardness of up to 9.3, second only to diamond, cubic boron nitride, and boron carbide.Therefore, it is widely used in the manufacturing of high-speed cutting tools, abrasives, and other fields.
2: High temperature resistance
The melting point of high-performance silicon carbide is around 2700 ° C, and its high-temperature resistance far exceeds that of traditional materials.In high-temperature environments, its physical and mechanical properties do not undergo significant changes, and it has good antioxidant properties.
3、 Strong corrosion resistance
Due to the fact that silicon carbide itself is an inorganic non-metallic material, its corrosion resistance is also very good.It can withstand strong corrosive media such as acid and alkali without significant damage.
4、 Superior thermal and conductive performance
Silicon carbide is a good thermal and conductive material, with high thermal and conductivity coefficients.In high-temperature environments, its thermal conductivity is particularly outstanding.5、 Good chemical stability
5: The chemical stability of silicon carbide is also very good.
It is not affected by reactions such as oxidation, reduction, hydrolysis, etc., so it can be used in various chemical environments.
6、 Excellent radiation resistance performance
Silicon carbide has good radiation resistance.In fields such as nuclear industry, it can be used as an important structural material.
7、 High mechanical strength
The mechanical strength of silicon carbide is also very high.It has good mechanical properties such as tensile resistance, bending resistance, and compression resistance.
8、 Low density
The density of carbonized bricks is relatively low, generally around 3.2-3.3g/cm3.Therefore, when manufacturing lightweight structural materials, silicon carbide can be chosen as the base material
9、 Easy to process and shape
Silicon carbide is easy to process and shape.It can manufacture products of various shapes and specifications through various methods such as injection molding, compression molding, and sintering molding
10、 Good wear resistance
The wear resistance of Baotong silicon carbide is also very good.It can maintain good wear resistance in high-speed friction and high-temperature environments
