Tóm tắt

Crystallization of V2O3 from V2O3P2O3, glasses containing 0 to 9 mol% B2O3, during heat treatment in the range 220° to 410°C, caused progressive micro structural changes which dramatically affected the electronic conductivity (γ), the activation energy for conduction (W), and the resistance to chemical attack. All compositions were ≊83% crystalline after heating to 410°C. As a result, the values of γ and W were almost identical to those observed for pure polycrystalline V2O5.
