Abstract

The structure of alkaline earth vanadate glasses of the compositions, xMO·(100-x)V2O5 (M = Mg, Ca, Sr, Ba, x = 30, 40, 45, 50, 55), has been investigated by means of IR spectroscopy with reference to various crystalline alkaline earth vanadates structurally known. It is found that the structure of alkaline earth vanadate glasses is very similar to each other and mainly consists of VO4-tetrahedra which form either (VO3)n-single chains as found in Sr(VO3)2 and Ba(VO3)2 crystals or the three dimensional arrangement of the corner-sharing branched VO4-tetrahedral groups as found in molten and amorphous V2O5. It is stressed that the glass network of the V2O5-rich glasses, 30MO·70V2O5, also mainly consists of VO4-tetrahedra.
