Microstructure, Electronic Properties and Chemical Durability of Vanadium-Pentoxide-Based Glasses and Glass-Ceramics.

Abstract

Crystallization of Vanadium Pentoxide from Vanadium Pentoxide-Phosphorous Pentoxide glasses containing 0-9 mol% Boron Trioxide during heat treatment in the range 220 C-410 C caused progressive microstructural changes which dramatically affected the electronic conductivity, the activation energy for conduction, and the resistance to chemical attack. All compositions were approximately 83% crystalline after heating to 410 C. As a result, the values of conductivity and activation energy were almost identical to those observed for pure polycrystalline Vanadium-Pentoxide. (Author)
