Abstract

This study presents a detailed comparison of the yellow chromate pigments strontium yellow SrCrO₄, barium yellow BaCrO₄, zinc yellow KZn₂(CrO₄)₂·H₂O(OH) and the rare cadmium chrome yellow 2CdCrO₄·KOH·H₂O, to allow their identification in fine art. Historical recipes from the late nineteenth century were used to synthesise these pigments to ensure they were prepared in an authentic manner. The characteristics of the pigments were established through X-ray diffraction (XRD), scanning electron microscopy (SEM), energy-dispersive X-ray spectroscopy (EDS), Raman spectroscopy and Fourier transform infrared spectroscopy (FTIR). The colour properties of the pigments and pigment-oil systems were evaluated using the CIE L*a*b* system. Zinc and cadmium chrome yellows showed the highest chroma and yellow contribution, while strontium yellow exhibited a significant degree of green hue and the lowest amount of yellow hue. The light stability of the chromate pigments tested is influenced by their elemental composition, method of synthesis and the surrounding medium.

十九世纪铬酸盐颜料：锶、钡、锌和镉铬黄的合成和质量比较

本文对黄色铬酸盐颜料锶黄SrCrO4、钡黄BaCrO4、锌黄KZn2(CrO4)2·H2O（OH）和稀有镉铬黄2CdCrO4·KOH·H2O进行了详细的比较，以便在美术品中进行鉴定。19世纪晚期的历史配方被用于合成这些颜料，以确保它们以真实的方式制备。通过x射线衍射（XRD）、扫描电镜（SEM）、能量色散x射线能谱（EDS）、拉曼光谱（Raman）和傅里叶变换红外光谱（FTIR）确定了颜料的特性。使用CIE L*a*b*系统对颜料和颜料-油体系的颜色特性进行了评价。锌和镉铬黄的色度和黄贡献最大，而锶黄的绿调程度显著，黄调程度最低。所测铬酸盐颜料的光稳定性受其元素组成、合成方法和周围介质的影响。图形抽象

期刊介绍： The Journal of Materials Science publishes reviews, full-length papers, and short Communications recording original research results on, or techniques for studying the relationship between structure, properties, and uses of materials. The subjects are seen from international and interdisciplinary perspectives covering areas including metals, ceramics, glasses, polymers, electrical materials, composite materials, fibers, nanostructured materials, nanocomposites, and biological and biomedical materials. The Journal of Materials Science is now firmly established as the leading source of primary communication for scientists investigating the structure and properties of all engineering materials.
