The Chemical Formula of Silicon Carbide, which is also known carborundum, is SiC. It is produced by the carbothermal reduction of silica to form an ultra-hard covalently bonded material. It is extremely rare in nature but can be found in the mineral moissanite, which was first discovered in Arizona in 1893.
In the past, carbide taps for high volume production were limited to materials such as brass, bronze and high silicon aluminum where abrasion was the cause of tool wear. The design required strength behind the cutting edge limiting the flute geometry and range of
2007/7/12· Silicon carbide has a specific gravity of 3.2, and its high melting point (approximately 2700 C.) makes silicon carbide useful for bearings and furnace parts. It is also highly inert chemically. SiC also has very low thermal expansion coefficient and no phase transitions that would cause discontinuities in thermal expansion.

Cast iron is a group of iron-carbon alloys with a carbon content more than 2%. Its usefulness derives from its relatively low melting temperature. The alloy constituents affect its colour when fractured: white cast iron has carbide impurities which allow cracks to pass straight through, grey cast iron has graphite flakes which deflect a passing crack and initiate countless new cracks as the
Silicon carbide is a sharper and harder grain compared to aluminum oxide, but silicon carbide is less durable because it is brittle and has a more narrow shape that wears down at an increased rate. Due to its razor-sharp grains, silicon carbide will have no problem easily …

Abstract Amorphous boron carbide films of 2 micron thickness were deposited at room temperature by a thermal deposition process on single-crystal silicon substrates. The elastic constants of an amorphous B 4 C film have been successfully measured by surface Brillouin stering as a function of temperature, in the process, revealing a phase transition at about 350 C.
