Abstract
Abstract Bi1−x−yCaxZnyVO4−(x+y)/2 (0 ≤ x ≤ 0.10, 0 ≤ y ≤ 0.10) pigments were synthesized as novel inorganic yellow pigments that are environmentally friendly, and their color properties were characterized. The Bi1−x−yCax–ZnyVO4−(x+y)/2 pigments exhibited brilliant yellow colors, and using the CIE L*a*b* system, the most vivid yellow hue was obtained for Bi0.90Ca0.08Zn0.02VO3.95 with a yellowness value (b*) that is larger than that of a commercially available bismuth vanadate yellow pigment. BiVO4 is an environmentally friendly inorganic yellow pigment, and Ca and Zn are also nontoxic elements; therefore, the Bi0.90Ca0.08Zn0.02VO3.95 pigment should be an effective alternative to conventional toxic yellow pigments.
