Rare-earth phosphides chemical properties

The present chapter consists of two main sections, presenting data about binary and ternary rare-earth phosphides, respectively. Section 1 deals with material on phase diagrams of R-P systems, the crystal structures of all known binary phosphides, their chemical properties, and methods of preparation. Section 2 contains similar information on ternary rare-earth phosphides, and additionally includes systematized data on physical properties and the valence state of lanthanoid atoms. 

Chemical properties of binary rare-earth phosphides... 

The chemical properties of the binary rare-earth phosphides have been studied fully only for monophosphides, their thermodynamic characteristics have also been determined. Thermodynamic data of formation and atomization of the R monophosphides are listed in table 19. 

Systematic investigation of the chemical properties of the ternary rare-earth phosphides has not been carried out. Some authors report chemical properties of some compounds. 

Kuz ma and Chykhrij present a systematic and encyclopedic discussion of the phosphides of the binary, ternary and quaternary rare earths. Their coverage includes preparation, phase diagrams, structure, as well as chemical and physical properties. The crystallochemical regularities, the nature of the interaction between components in ternary systems, and structural relationships also constitute important aspects of this review.
