Calcium carbide, chemically known as calcium carbide (CaC2), is a black gray or purple brown solid block, while pure calcium carbide is a colorless cubic crystal. It has the following characteristics:
Calcium carbide is odorless, but after hydrolysis, industrial calcium carbide generates various gases, including irritating toxic gases such as PH3, H2S, NH3, etc.
The melting point of calcium carbide is approximately between 1800~2200 ° C, while the melting point of pure calcium carbide is 2300 ° C.
The density of calcium carbide depends on its purity, with higher purity resulting in lower relative density.
The quality of calcium carbide is related to its hardness. The lower the quality, the higher the density, and the harder it becomes.
Calcium carbide easily absorbs moisture from the air, causing its cross-section to lose luster and turn gray white.
Calcium carbide is a conductive material, and its conductivity increases with increasing purity and temperature.
