Tungsten: Properties, Production, Appliions & Alloys
8/12/2019· Tungsten carbide is produced either by bonding one tungsten atom with a single carbon atom (represented by the chemical syol WC) or two tungsten atoms with a single carbon atom (W2C). It is done by heating tungsten powder with carbon at temperatures of 2550°F to 2900°F (1400°C to 1600°C) in a stream of hydrogen gas.

Silicon - High Precision Machining - Insaco
Silicon is well known as a key component of electronic devices and also of solar cells. For these appliions, the silicon must be purified from its initial form. Silicon is certainly a readily available raw material since it is actually the third most abundant element on Earth after only iron and oxygen, and is handy to isolate from common sand by reduction with coke in the presence of iron.
