Machining Of Silicon Carbide

Mar 03, 2006· There is also chemical vapor deposited silicon carbide called CVD Silicon Carbide, which is an extremely pure form of the compound. To sinter the Silicon Carbide its is necessary to add sintering aids which help to form a liquid phase at the sintering temperature which allows the grains of silicon carbide to bond together.

Calcium carbide - Wikipedia

The reaction of calcium carbide with water, producing acetylene and calcium hydroxide, was discovered by Friedrich Wöhler in 1862. CaC 2 + 2H 2 O → C 2 H 2 + Ca(OH) 2 (aq) This reaction was the basis of the industrial manufacture of acetylene, and is the major industrial use of calcium carbide.
