The distribution and chemical states of vanadium in V-doped ZrO[sub 2] were studied to clarify the origin of the color of vanadium-zirconium yellow pigment in comparison with vanadium-tin yellow pigment. ESCA data and measurements of lattice constants of V-doped ZrO[sub 2] revealed that vanadium was dissolved mainly as V[sup 4+] substituting for Zr in ZrO[sub 2] lattice, and its solubility limit was 0.5 wt% as V[sub 2]O[sub 5]. It was found that the yellow color of vanadium-zirconium yellow was produced predominantly by the dissolved vanadium and that the contribution of vanadium oxide on ZrO[sub 2] grains to the yellow color was about 1.30 of that of the dissolved vanadium when compared on the basis of equimolar quantity of vanadium. Most of the undissolved vanadium oxide was in an amorphous or a poorly crystallized state.
