本文采用固相法以(NH_4)_2HPO_4、ZrO_2和Ni_2O_3为原料制备了新型Ni_(0.5)Zr_2(PO_4)_3红色陶瓷色料,研究了不同Ni_2O_3的加入量对色料呈色性能的影响。结果表明:Ni_2O_3的添加量为6%时在烧成温度为1400℃、保温时间为1h、色料的红色最好,其色度指数为:L*=68.53,a*=23.20,b*=11.07;通过XRD、TG-DTA和紫外-可见光分光光度法等测试的分析说明,色料呈现红色可能是因为合成了Ni_(0.5)Zr_2(PO_4)_3而Ni~(2+)在磷酸锆中呈现红色所致。
In this work, the new Ni_(0.5)Zr_2(PO_4)_3 red pigments were synthesized using.(NH_4)_2HPO_4, ZrO_2 and Ni_2O_3 as the raw materials. The effects of different addition of Ni_2O_3 on the chromatic properties of the ceramic pigments were investigated. The results manifested that when the addition of Ni_2O_3 is 6%, the firing temperature of the nickel zirconium phosphate pigment is 1400 °C, and the holding time is 1 h, the color of the pigment is red and the color is the best and the chromatic data is L*=68.53, a*=23.20 and b*=11.07. XRD, TG-DTA and UV-VIS spectrophotometry showed that the pigment's color was red due to the presence of Ni~(2+) of Ni_(0.5)Zr_2(PO_4)_3.
