In many cases the excess of volatile ingredients Al Ga Si is used due to the possible loss of this element during high-temperature treatment flow of inert gas and conversion to oxides by reaction with oxygen contamination from starting materials 172 173.
The Δ H f Δ H f of CaC 2 is 1514 kcalmol.
Calcium carbide molar mass. Calcium carbide also known as calcium acetylide is a chemical compound with the chemical formula of Ca C 2. 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 8085 of CaC 2 the rest is CaO calcium oxide.

The molar mass of a substance also often called molecular mass or molecular weight although the definitions are not strictly identical but it is only sensitive in very defined areas is the weight of a defined amount of molecules of the substance a mole and is expressed in gmol. It can be calculated by adding the invididual molar mass of every atom that are composing the molecule CH4.
