铬钴绿色料的制备

Preparation of Cobalt Doped Chrome Green Pigment

以三氧化二铬、氧化钴为主要原料,氧化锌和磷酸二氢铵为辅助助剂,采用固相反应法制备了铬钴绿色料。通过正交实验设计进行了配方优化,并进行了相应分析。实验和分析结果表明:在铬钴绿色料合成过程中,氧化锌的掺量对色料的调节影响作用最大,氧化钴的掺量对色料颜色的影响作用较小。最佳配方组成为三氧化二铬100%,氧化钴4%,氧化锌6%,磷酸二氢铵8%。

The cobalt doped chromium pigment was prepared by solid state reaction route while the chromium oxide, cobalt oxide as the main raw material, zinc oxide and ammonium dihydrogen phos- phate as auxiliary aids. Experimental and analytical results based on the orthogonal experimental de- sign show that the content of zinc oxide has the greatest impact on the color of pigment, however the content of cobalt oxide plays smaller r01e in the synthesis process. The best formulation consists of chromium oxide 100%, cobalt oxide 4%, zinc oxide 6%, ammonium dihydrogen phosphate 8%.
