The System CaO-CaF2.

Abstract

In studies on the electrical conductivity of the system.Ca0-Ca.F1 ithasbeenshown that there exists a gap of miscibility in the liquid state on the CaF2 rich side of the diagram. Previously this system had only superficially been studied by Eitel 1 as part of a greater work with the method of thermal analysis. In his work, he reported a value for the eutectic point. However, Eitel did not use the highest grade of purity of CaF I and thus found a melting point for the fluoride which was too low. The true melting point has been determined by Naylor I and found to coincide with the one in this work.
