Vanadium-tin composite oxides are rather widely used as, for example, yellow pigments for coloring glazes and selective oxidation catalysts for hydrocarbons. Physicochemical states of vanadium in V-doped SnO[sub 2] 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 SnO[sub 2] revealed that vanadium was dissolved as V[sup 4+] and its solubility limit was 0.9 wt% as V[sub 2]O[sub 5]. It was found that the color of vanadium-tin yellow was produced by two types of undissolved vanadium on SnO[sub 2] grains. One is poorly crystallized vanadium oxide (v), (V[sub 2]O[sub 5])[prime], having a yellow color, and the other is orange-colored crystalline V[sub 2]O[sub 5]. The structure of (V[sub 2]O[sub 5])[prime] was discussed in connection with its color.
