Its density is 2.52g/cm3 and melting point is 2450, Because of its high strength, low density, corrosion resistant, high temperature resistant, low thermal conductivity, high modulus of elasticity, it is an ideal material for a wide variety of appliions.
Silicon carbide was discovered by Dr. Edward Goodrich Acheson. It was the first man made abrasive and known to be very hard substance. It has high melting point and acts as thermal insulator
Silicon carbide is a very popular abrasive in modern lapidary owing to its durability and the relatively low cost of the material. It is, therefore, crucial to the art industry. In the manufacturing industry, this compound is used for its hardness in several abrasive machining processes such as honing, grinding, water-jet cutting, and sandblasting.
2019/10/2· They do infer melting from the inability of low melting point polishers to polish high melting point materials even though hardness might be lower in the polished material. Not trying to confirm my bias with a 1936 article nonetheless, I will concede the subject is orders of magnitude more complex than I previously thought.

1974/12/3· The first two silicon carbide powders were commercial abrasive quality and the latter silicon carbide was prepared by wet ball milling and acid leaching of the 600 mesh silicon carbide. The slip was poured into the graphite die and the dispersant …
Abrasive paperhas the grains, usually alu-minum oxide or silicon carbide, glued to one side of 40- to 130-lb kraft paper. The usual grain sizes are No. 16 to No. 500. Abrasive powderis usually graded in sizes from 8 to 240 mesh. Coarse grain is to 24 mesh; fine
2020/7/9· Boron carbide is characterized by a unique coination of properties that make it a material of choice for a wide range of engineering appliions. Boron carbide is used in refractory appliions due to its high melting point and thermal stability; it is used as abrasive powders and coatings due to its extreme abrasion resistance; it excels in ballistic performance due to its high hardness
Silicon carbide ceramics with little or no grain boundary impurities maintain their strength to very high temperatures, approaching 1600 C with no strength loss. Chemical purity, resistance to chemical attack at temperature, and strength retention at high temperatures has made this material very popular as wafer tray supports and paddles in semiconductor furnaces.
