Crystallization of V 2 O 3 from V 2 O 3 P 2 O 3 , glasses containing 0 to 9 mol% B 2 O 3 , 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 V 2 O 5 .
