Abstract

Moissan first showed in a qualitative way that hydrogen and calcium form a combination which is very little dissociated below 700 degrees C. He also showed that this compound can be expressed by the chemical formula CaH2 and seemed to be a well defined compound. Gautier makes a statement that calcium hydride begins to dissociate as soon as the hydrides of strontium and barium (about 675 degrees C.) Moldenhauer and Roll-Hansen made a systematic study of the dissociation from 780 degrees C. to 1027 degrees C. These workers point out that the equilibrium pressures may be masked by the action of the calcium and calcium hydride on the reaction vessel.
