Calcium Carbide - an overview | ScienceDirect Topics

Calcium carbide is also an intermediate product in the smelting of calcium–silicon alloy. Technical grade calcium carbide is crystallized from the melt and contains ~80% CaC2 and 10% to 15% CaO (Fig. 19.4). Commercial calcium carbide is a gray-black material due to the presence of residual carbon.

Calcium carbide (cas 75-20-7) SDS(Safety Data Sheet)

Calcium carbide incandesces with chlorine, bromine, or iodine at 245, 350, or 305\u00b0C., respectively, [Mellor, 1946, Vol. 5, 862]. The carbide burns incandescently when mixed and heated with lead difluoride, magnesium, hydrogen chloride, and tin (II) chloride, [Mellor, 1946, 1940, 1946, and 1941], respectively.
