摘要
本文从晶体结构和谱学特征探讨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Zr_(1-(x+y))Cr_xR_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.
This paper has made an approach to the colouring mechanism of zircon rare-earth ceramic pigment from the crystal structure and spectrometric property. The lattice constant, the lattice dcformation and spectro-reflection coefficient of Zr_(1-(x+y))Cr_xPr_ySiO_4 have been studied by means of XRD internal standardization and spectrophotometer. It has been discovered that Pr^(3+) make lattice expanding and deforming, thus causing changes is optical properties of the pigment.
