Abstract

Vanadium-containing yellow pigment was deposited onto marshalite particles through solution-combustion reaction of V₂O₅ with salts of Bi, Zn, and Ca using citric acid as a fuel and characterized by XRD, FT-IR spectra, and SEM. Yellow color of the pigment was due to the presence of bismuth vanadate BiVO₄. Minor impurity of Bi₄V₂O₁₁ by-product imparted a beige hue to the pigment. The addition of Zn²⁺ and Ca²⁺ cations improved the chromatic characteristics of the pigment. Size distribution of resultant pigment is defined by that of mineral substrate powder. Our pigments were heat resistant and retained their color up to 800°С.

通过溶液-燃烧反应将含钒黄色颜料沉积到 Marshalite 颗粒上

摘要

以柠檬酸为燃料，通过V ₂ O ₅与Bi、Zn 和Ca 盐的溶液燃烧反应，将含钒黄色颜料沉积在marshalite 颗粒上，并通过XRD、FT-IR 光谱和SEM 进行表征。颜料的黄色是由于钒酸铋BiVO ₄的存在。Bi ₄ V ₂ O ₁₁副产物的少量杂质赋予颜料米色色调。Zn ²⁺和Ca ²⁺阳离子的加入改善了颜料的色度特性。所得颜料的粒度分布由矿物基质粉末的粒度分布决定。我们的颜料具有耐热性，并且在高达 800°С 的温度下仍能保持颜色。
