摘要：

Physicochemical states of vanadium in V-doped SnO2 were studied to clarify the origin of the color of vanadium-tin yellow pigment and its color instability when fired with glaze material. Precision measurements of lattice parameters of V-doped SnO2 revealed that vanadium was dissolved as V4+ and its solubility limit was 0.9 wt% as V2O5. It was found that the color of vanadium-tin yellow was produced by two types of undissolved vanadium on SnO2 grains. One is poorly crystallized vandium oxide (v), (V2O5)', having a yellow color, and the other is orange-colored crystalline V2O5. The structure of (V2O5)' was discussed in connection with its color.
