Phase Relationships in the Calcium Chloride – Calcium Carbide System

Canadian Journal of Chemistry, 1972
The system calcium chloride – calcium carbide has been examined by thermal analysis. The depression of the freezing point of CaCl2 by CaC2 is ideal. The system is a eutectic one, with a eutectic point at 90 mol% CaCl2 at 740 °C. Carbon is believed to be present in the electrolyte as the so called acetylide ion [Formula: see text] The melting point of ...

Thermodynamic Analysis of Calcium Carbide Production

Industrial & Engineering Chemistry Research, 2014
CaC2 production is studied from the viewpoint of thermodynamics using an equilibrium composition model with total Gibbs free energy minimization. It is found that CaC2 is formed directly from the reaction of C and CaO without an intermediate step under the conditions of industrial practice.
