Embodiment 1
[0043]
[0044] Vanadium oxide glass A having ion conductivity and ferroelectricity, and vanadium oxide glass B having only ion conductivity were prepared. As a raw material, vanadium pentoxide (V 2 o 5 ), phosphorus pentoxide (P 2 o 5 ), tellurium dioxide (TeO 2 ), ferric oxide (Fe 2 o 3 ), barium carbonate (BaCO 3 ), titanium dioxide (TiO 2 ). As the raw material composition of glass A, the molar ratio of various raw materials is: V 2 o 5 :P 2 o 5 :TeO 2 :Fe 2 o 3 :TiO 2 :BaCO 3 =36.2:10:23.1:7.7:11.5:11.5. In addition, as the raw material composition of glass B, the molar ratio of various raw materials is: V 2 o 5 :P 2 o 5 :TeO 2 :Fe 2 o 3 =55:14:22:9. These raw material powders were put into a platinum crucible, and heated at 1100°C for 1 hour in an electric furnace. Also, during heating, stir the raw materials in the platinum crucible to achieve uniformity. Then, the platinum crucible was taken out from the electric furnace, spread on a stainl...

[0061]
[0062] Two types of ion-conductive vanadium oxide glasses with different softening points were produced. As a raw material, vanadium pentoxide (V 2 o 5 ), phosphorus pentoxide (P 2 o 5 ), tellurium dioxide (TeO 2 ) powder, ferric oxide (Fe 2 o 3 ). As the raw material composition of glass A with a high softening point, the molar ratio of various raw materials is V 2 o 5 :P 2 o 5 :TeO 2 :Fe 2 o 3 = 47:13:30:10. In addition, as the raw material composition of glass B with a low softening point, the molar ratio is V 2 o 5 :P 2 o 5 :TeO 2 :Fe 2 o 3 =55:14:22:9. These raw material powders were put into a platinum crucible, and heated at 1100°C for 1 hour in an electric furnace. Also, stir during heating to make the raw materials in the platinum crucible uniform. Then, the platinum crucible was taken out from the electric furnace, spread on a stainless steel plate preheated to 150°C, and cooled naturally to obtain vanadium oxide glass. The softenin...
