Calcium carbide (also known as calcium acetylide) is a chemical compound with the formula CaC2. It is a colorless or white powder, however it is grey/brow/black crystals if impure.
Production
It is made by heating a mixture of lime (calcium oxide) and coke (fuel) to upwards of 2200°C. Although this can be achieved at slightly lower temperatures, the carbon monoxide will not decompose or react with substances in the air, thus creating a hazard. This is not recommended with traditional combustion (such as wood kilns or open flames) due to difficulties in attaining a high temperature for a sufficiently long duration, instead use of a method such as an electric arc furnace is encouraged.
CaO() + 3 C(s) → CaC2() + CO(g)
Uses
Acetylene and calcium hydroxide production through the reaction with water.
