【摘要】 本文采用固相法以（NH₄）₂HPO₄、ZrO₂为原料,Ni₂O₃为着色剂,制备磷酸锆基高温红色色料,研究了六种不同单一矿化剂对陶瓷色料的呈色性能的影响,以及矿化剂ZnO的添加量对磷酸锆基高温红色色料性能的影响。通过XRD和紫外线可见光分光光度法对色料进行物相和色度分析。实验结果表明:在磷酸锆基高温红色色料中矿化剂的添加有利于色料的颜色更红更鲜艳,六种矿化剂的作用效果为ZnO>KNO₃>NaCl>H₃BO₃>NH₄Cl>CaCl₂。当ZnO含量为0¹%时,由于Zr₂O（PO₄）₂少量的合成,色料的红色更亮,更鲜艳;继续增加ZnO含量（大于1%）时,ZnO的加入会使晶格活化,促进晶体Zr₂O（PO₄）₂的合成,致使主晶相由Ni_0.5Zr₂（PO₄）₃转变为Zr₂O（PO₄）₂,过多的Zr₂O（PO₄）₂导致色料吸收光的波长范围发生偏移,从而导致色料的颜色从红色变成黄色。更多还原

【Abstract】 High temperature red pigments based on zirconium phosphate were synthesized by solid state reaction method,in which（NH₄）₂HPO₄and ZrO₂ were used as raw materials and Ni₂O₃ as the cooling agent.Effects of six unitary mineralizers on performance of the pigment were investigated,particularly the influence of ZnO addition on the performance of Ni_0.5Zr₂（PO₄）₃red pigment.XRD and UV-VIS spectrophotometer were employed to analyze the phase and color of the pigments.Experimental results showed that adding mineralizers can make high-temperature red pigments based on zirconium phosphate more colorful and redder.Effects of the mineralizers can be simply in the descending order as follows:ZnO>KNO₃>NaCl>H₃BO₃>NH₄Cl>CaCl₂.When the ZnO content is 0¹%,the pigment color was still red but more bright as a few of Zr₂O（PO₄）₂was synthesized.When the ZnO content was more than 1%,Zr₂O（PO₄）₂formed and the main phase changed from the Ni0.5Zr₂（PO₄）₃to Zr₂O（PO₄）₂due to the lattice activation by ZnO.Superfluous Zr₂O（PO₄）₂led to wavelength shift of the absorbing light from red to yellow.更多还原
