Silicon carbide characteristics
Silicon carbide is a new type of inorganic non -metallic material. It has many excellent characteristics and is widely used in electronics, photoelectric, chemical, metallurgy and other fields. Its main characteristics are as follows:
1. High hardness
Silicon carbide has extremely high hardness, and its Mohs can reach 9.3, second only to diamond and cubic boron nitride and boron carbide. Therefore, it is widely used in manufacturing high -speed cutting tools and abrasives.
2.: high temperature resistance
The melting point of the performance of silicon carbide is about 2700 ° C, and its high temperature resistance is far more than traditional materials. In high temperature environments, their physical and mechanical properties will not change significantly, and they have good antioxidant performance.
3. Strong corrosion resistance
Since silicon carbide itself is a kind of inorganic non -metallic material, its corrosion resistance is also very good. It can tolerate the erosion of strong corrosive media such as acid and alkali and does not cause obvious damage.
4, superior thermal conductivity and conductivity
Silicon carbide is a good thermal conductivity, and its heating coefficient and conductive coefficient are relatively high. In high temperature environments, its thermal conductivity performance is better. 5. Good chemical stability
5: The chemical stability of silicon carbide is also very good.
It is not affected by reactions such as oxidation, restoration, and hydrolysis, so it can be used in various chemical environments.
6. Excellent anti -radiation performance
Silicon carbide has good radiation resistance. In the field of 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 stretching, bending and compression.
8. Low density
The density of carbonized bricks is relatively low, generally about 3.2-3.3g/cm3. Therefore, when making light structure materials, you can choose silicon carbide as the basic material
9. Easy to process
Silicon carbide is easy to process. It can create products of various shapes and specifications through various methods such as modeling molding, suppressing molding, and sintering molding
10. Good abrasion resistance
The wear resistance of silicon carbide is also very good. It can maintain good wear resistance in high -speed friction and high temperature environment
