镨锰铬紫色陶瓷颜料的合成研究

以氧化锰、氧化铬、氧化镨等为原料 ,采用均匀共沉淀法在1100℃下保温2h ,合成了镨锰铬紫色陶瓷颜料 ,并采用颜色测定、SEM、XRD及能谱分析等手段对颜料的颜色、粒度及结晶构造等进行了表征。结果表明 :掺杂Pr离子后 ,颜料由棕褐色变为紫色 ,而且可以稳定于1320℃的高温陶瓷釉料中。

The Mn1.5Cr1.5O4 violet ceramic pigment added with Pr ion has been synthesized for the first time at home in temperature 1100℃ by using precipitation method. The color, particle size and crystalline structure have been characterized by color measuring and SEM. XRD analyzing. Results show, the color of the pigment convert from dark brown to violet after added Pr ion. The pigment can be used in a high temperature glaze under 1320℃.
