Carbide vs Tungsten Carbide in tool realm

2017-6-24 · I realize that there are different techniques for binding carbide into a final tool shape, however by question is on a lower chemistry level. Carbide by it''s strict definition is a binary compound of carbon with a lower electro-negativity element. So in theory there are many types of carbide: boron carbide, calcium carbide, tungsten carbide etc.

Silicon Carbide (SiC) Properties and Appliions

Silicon carbide is a hard covalently bonded material predominantly produced by the carbothermal reduction of silica (typically using the Acheson process). Several commercial grades of silicon carbide exist such as nitride bonded, sintered, reaction bonded, SiAlON bonded and clay bonded.

Silicon - Corrosionsource

Silicon makes up 25.7% of the earth''s crust, by weight, and is the second most abundant element, being exceeded only by oxygen. Silicon is not found free in nature, but occurs chiefly as the oxide and as silies. Sand, quartz, rock crystal, amathyst, agate, flint, jasper, and opal are some of the forms in which the oxide appears.
