Rock Tuler Grit and Silicon Carbide Grit Kits
1) Silicon carbide grit is very hard. It is much harder than the rocks that most people tule. On the Mohs Hardness scale silicon carbide has a hardness of 9 to 9.5 while commonly-tuled rocks such as jasper, agate, quartz and petrified wood have a Mohs Hardness of about 7. This means that silicon carbide grit can easily abrade the rocks that

Silicon Carbide - Reaction Bonded Rod - online alogue
To manufacture Reaction Bonded Silicon Carbide (RBSC), Silicon is infiltrated into a pre-formed silicon carbide/carbon powder green body which is then fired. This gives rise to around 10% free silicon, which fills the pores. The resulting microstructure has low porosity and a very fine grain.
Buy Sapphire Online - Wafer
Sapphire wafers are manufactured from single crystal sapphire ingot, making them ideal for demanding appliions (such as laser systems) because of their extreme surface hardness, high thermal conductivity, high dielectric constant and resistance to common chemical acids and alkalis.

Calcium carbide - Wikipedia
The pure material is colorless, however pieces of technical-grade calcium carbide are grey or brown and consist of about 80–85% of CaC 2 (the rest is CaO (calcium oxide), Ca 3 P 2 (calcium phosphide), CaS (calcium sulfide), Ca 3 N 2 (calcium nitride), SiC (silicon carbide), etc.).In the presence of trace moisture, technical-grade calcium carbide emits an unpleasant odor reminiscent of garlic.

Synthesis of silicon carbide through the sol-gel process
Silicon carbide (SiC) was synthesised from silicon alkoxides and various carbon sources. Tetraethoxysilane (TEOS), methyltriethoxysilane (MTES) and a mixture of TEOS and MTES were hydrolysed in the presence of phenolic resin, ethylcellulose, polyacrylonitrile (PAN) and starch to incorporate the gel into the carbon source in the silica network. The gel thus obtained was carbonized …
