The results are given of a study of the gaseous products liberated during the decomposition of the carbide phases of the rare-earth metals by water. These products consist mainly of acetylene, ethylene, methane, ethane, and also hydrogen. From an analysis of the composition of the gaseous products in conjunction with an analysis of data on some of their physical properties, it is shown that with increase in the C/Me ratio of the carbides of the rare-earth metals, the nature of the chemical bond changes from being predominantly ionic in MeC phases to being predominantly covalent-metallic in MeC2 phases.
