Rare-earth bismuthides

Add time:08/25/2019    Source:sciencedirect.com

The binary systems of the rare-earth elements (except Eu and Lu) with bismuth, have been examined using X-ray and metallographic techniques. The phases identified were RBi2 (LaBi2-type), RBi (NaCl-type), R4Bi3 (antiTh3P4-type), R5Bi3 (Mn5Si3-type), R5+xBi3 (Y5Bi3-type) and R2Bi (La2Sbtype). The LaBi2-type structure is new and single-crystal studies are reported. Refined lattice parameters are given for all the phases. Studies of the system ytterbium-bismuth are incomplete but reveal that it differs markedly from the other binary systems.
