Calcium carbide also known as calcium acetylide is a chemical compound with the chemical formula of Ca C 2 s 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 CaC 2 (the rest is CaO (calcium oxide) Ca 3 P 2 (calcium phosphide

Calcium carbide Wikipedia Calcium carbide is sometimes used as source of acetylene gas which is a ripening agent similar to ethylene However this is illegal in some countries as in the production of acetylene from calcium carbide contamination often leads to trace production of phosphine and arsine

Boron carbide can be used as a powder with various grain sizes or as a ceramic component To manufacture ceramic components with high relative density fine boron carbide powder with sinter additives is moved processed with conventional ceramic-shaping methods and sintered or hot press-molded at temperatures above 2 000 C in an inert gas atmosphere
