摘要
考察了稀土元素的呈色效果和组合着色锆英石型颜料的物相变化过程.从晶体结构和谱学特征探讨了锆英石型稀土陶瓷颜料的呈色机理.利用 XRD 内标法和分光光度计研究了Zr_(1-(x+y))Cr_xPr_ySiO_4的晶格常数、晶格畸变和分光反射率.发现 Pr^(3+)离子使晶格胀大、产生畸变,从而导致光学性质的变化.
Colour generation effect of rare-earth elements and the phase change process of group colourant zircon pigment have been investigated.From crystal construction and spectroscopy char- acteristic,colour generation mechanism of zircon rare-earth ceramic pigment has been discussed. Latice constant,lattice distortion and spectro-reflectance of Zr<sub>1-（x+y）</sub>Cr<sub>x</sub>Pr<sub>y</sub>SiO<sub>4</sub>have been studied by using XRD interior label method.It is found that Pr<sup>3+</sup>ion makes lattice expand,causing distortion and leading to changes in optical property.
