Ternary Nitrides, Phosphides, and Arsenides of Lithium

Abstract

Abstract Ternary phases have been prepared from lithium, another metal, and nitrogen, phosphorus, or arsenic. The ternary compounds, in particular the nitrides, are thermally more stable than the binary compounds. The lithium gives rise to a relatively high polar bonding component. At high temperatures, lithium and the second metal are often randomly distributed among the interstices of the metalloid lattice. The ordering processes that take place with decreasing temperature are investigated by X‐ray and magnetic methods and by differential thermal analysis. The phases are classified on a structural basis into seven groups.
