Study of the stable tetrahedra LiF–KBr–LiKMoO4–LiKWO4 and LiF–KBr–K2MoO4–K2WO4 of the quinary reciprocal system Li,K∥F,Br,MoO4,WO4

Abstract

The stable tetrahedra LiF–KBr–LiKMoO₄–LiKWO₄ and LiF–KBr–K₂MoO₄–K₂WO₄ of the quinary reciprocal system Li,K||F,Br,MoO₄,WO₄ were studied by differential thermal and X-ray powder diffraction analyses. It was determined that the tetrahedra contain no invariant points. Continuous series of solid solutions LiKMo_xW_1–xO₄ and K₂Mo_xW_1–xO₄ do not decompose.
