A STEP CHANGE IN CALCIUM CARBIDE PRODUCTION

Calcium carbide production continued to expand rapidly into the 20th century and by the late 1950s and into the early 1960s the carbide chemicals industry was at its peak, with world production of calcium carbide estimated at well over eight (8) million tonnes per year (1962), with more than 90% of this in North America, Europe and the Soviet Un-

Calcium Carbide an overview ScienceDirect Topics

The equipment used for the smelting of calcium carbide is similar to that employed in electric furnaces used for other forms of ferroalloys processing, where carbon is used as a reductant. 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% CaC 2 and 10% to 15% CaO (Fig. 19.4).

Calcium carbide Wikipedia

Calcium carbide, also known as calcium acetylide, is a chemical compound with the chemical formula of CaC2. Its main use industrially is in the production of acetylene and calcium cyanamide. The pure material is colorless, however pieces of technical-grade calcium carbide are grey or brown and consist of about 80–85% of CaC2 (the rest is CaO (calcium oxide), Ca3P2 (calcium phosphide), CaS (calcium sulfide), Ca3N2 (calcium nitride), SiC (silicon carbide), etc.). In the presence of trace moisture
