Structure and other physical properties of magnesium vanadate glasses

Abstract

Structure and other physical properties of (100-x)MgO-xV₂O₅ glasses of different compositions are reported in this paper. Different studies like X-ray diffractograms and oxygen molar volume show that homogeneous glasses are obtained in the composition domain x=60-90 mol%. It has been observed that the network structure for all glass compositions is built up of VO₄ polyhedra. The glass transition temperatures are observed to decrease with an increase in V₂O₅ content in the compositions. An increase in the concentration of the reduced V⁴⁺ ions with an increase in V₂O₅ content is observed from the magnetic susceptibility studies.
