Black zirconium oxide powder for ceramic mobile phone shell and preparation method thereof
The invention discloses a preparation method of black zirconium oxide powder for a ceramic mobile phone shell. The preparation method comprises the following steps: preparing a black pigment based on zirconium oxide, mixing the black pigment with white zirconium oxide raw powder according to a certain ratio, calcining, sintering, carrying out ball-milling dispersion, and drying to obtain the product. The black pigment is prepared by the following steps: dissolving a soluble zirconium compound, a soluble manganese compound, a soluble chromium compound, a soluble iron compound and a soluble cobalt compound in water according to a certain ratio, adding yttrium oxide as a stabilizer, carrying out precipitation reaction with ammonia water to obtain black zirconium hydroxide precipitate slurry, carrying out hydrothermal reaction to obtain black zirconium hydroxide precipitate, And drying, carrying out thermal decomposition treatment, and crushing. The black zirconium oxide powder disclosed by the invention is colored by metal oxide, is good in color stability and has good phase stability, and powder particles reach a nanoscale.
本发明公开了一种陶瓷手机壳用黑色氧化锆粉体的制备方法。该制备方法，首先制备基于氧化锆的黑色色料，然后将黑色色料和白色的氧化锆原粉按一定比例混合，再经煅烧烧结、球磨分散、烘干后制备获得。其中黑色色料以溶解性锆化合物、溶解性锰化合物、溶解性铬化合物、溶解性铁化合物、溶解性钴化合物按一定比例用水溶解，配以氧化钇作为稳定剂，经和氨水的沉淀反应得到黑色的氢氧化锆沉淀浆料，再经水热反应得到黑色氧化锆沉淀，再经干燥、热分解处理、破碎处理获得。本发明的黑色氧化锆粉体以金属氧化物着色，颜色稳定性好，并且具有良好的相稳定性，粉体颗粒达到纳米级。
