抄録
Polycrystalline samples of LaRh3Bx and LuRh3Bx have been successfully synthesized by the arc melting method. Stoichiometric compositions of LaRh3B and LuRh3B have the perovskite-type cubic structure (space group Pm3m) and lattice parameter a=0.4251(1)nm and a=0.4126(1)nm, respectively. LaRh3B has no nonstoichiometry of boron. On the other hand, perovskite-type LuRh3Bx exists in the range of 0.3≤x≤1.000; the lattice parameter a of the perovskite-type cubic cell increases with increasing boron content x in the compound. The stoichiometric LaRh3B and LuRh3B have micro-Vickers hardness of 4.2 (±0.1) GPa and 7.7 (±0.5) GPa, respectively. The hardness of the LuRh3Bx increases with increasing the B content.
