Abstract

Perovskite-type ScRh₃B and ScRh₃C form a continuous solid solution, ScRh₃B_xC_1-x, in the range of 0 ≦ x ≦ 1 with cubic structure (space group: Pm3m, Z = 1). The microhardness of the ScRh₃B_xC_1-x phase increases with increasing boron content. Thermogravimetric analysis of this phase indicates that the oxidation onset temperature also increases with boron content. Thus, it appears that the mechanical strength and chemical stability of the ScRh₃B_xC_1-x phase strongly depend on its boron content.
