The Synthesis and Characterization of Some Rare Earth Arsenides

Solid solutions of a new material, Holmium Niobium Arsenide, have been synthesized, and the binary arsenides NdAs and HoAs have been prepared. Chemical analyses have shown that both were arsenic deficient. Lattice parameters were determined for NdAs and HoAs. It has been established that a range of...

Description
Summary:Solid solutions of a new material, Holmium Niobium Arsenide, have been synthesized, and the binary arsenides NdAs and HoAs have been prepared. Chemical analyses have shown that both were arsenic deficient. Lattice parameters were determined for NdAs and HoAs. It has been established that a range of arsenic solubility exists in the binary arsenides where no change in lattice parameter is observed. High temperature thermal analyses were conducted on all arsenides. NdAs and HoAs exhibited arenic volatilization upon heating. Keywords: Rare earth arsenides, Lattice parameter, Holmium neodymium, Arsenide solid solution.
