Abrasive Silicon Carbide Sic for Diamond Tool
Description:
Pure silicon carbide without impurities should be colorless and
transparent. The silicon carbide used in industry ranges from
colorless to green, green to blue, and then even black. The
different colors of silicon carbide are mostly related to its
purity. According to research, boron can make silicon carbide
black, and when there is more carbon in the silicon carbide
crystal, its color is also black. Aluminum has a great influence on
the color of silicon carbide crystals, which can make silicon
carbide appear brown or black.
The oxidizability of silicon carbide is closely related to its own
chemical stability. According to thermodynamic calculations,
silicon carbide itself is very easy to oxidize, but the time
oxidation graph of silicon carbide is parabolic. This is because
when the temperature reaches a certain height, the silicon dioxide
generated by its oxidation forms a thin film, which gradually
hinders the oxidation process. In the oxidation process in the air,
when the temperature is 800℃, silicon carbide has already begun to
oxidize, and the reaction is slow. As the reaction temperature
continues to rise, the oxidation rate increases rapidly.
When the temperature reaches about 1600℃, the oxidation almost
stagnates. This is because the generated silicon dioxide layer
reaches a certain thickness, which protects silicon carbide and
hinders the continued oxidation. The oxidation rate of silicon
carbide in oxygen is 1.6 times faster than that in air.
