摘　　要：以Ca3(PO3)2、滑石、石英及硼熔块为基本组成,研制了无乳浊剂R2O-RO-Al2O3-SiO2-P2O5-B2O3体系环境友好型高白乳浊釉。通过X射线衍射及扫描电镜分析,研究了不同B2O3/P2O5质量比和烧成温度对釉面性能及釉的显微结构等的影响,并对磷硼多相乳浊釉的乳浊机理进行了分析。结果表明:在B2O3/P2O5质量比为1/2～2区域,1200℃烧成温度,可以得到白度较高的乳浊釉;B2O3/P2O5质量比不同时,釉熔体产生多次不混溶相,出现微相功能转换,乳浊度也随之改变;B2O3/P2O5质量比为1时,釉中分相小滴相对较多,尺寸与可见光相近,且分散性高,使釉对光的折射与散射能力强,釉面呈现高乳白效果,白度可达87。Multiphase opalescent glaze in R2O-RO-Al2O3-SiO2-P2O5-B2O3 system was fabricated with Ca3（PO3）2,talc,quartz and B2O3 frit as raw materials.Effects of the composition,B2O3 to P2O5 mole ratio and sintering temperature on the capability and macrostructure of the glaze were studied with scanning electron microscopy,and X-ray diffraction.The opacifying mechanism for phosphor-boron multiphase opalescent glaze was also analyzed.The results indicate that the high whiteness opalescent glaze can be prepared with the B2O3 to P2O5 mole ratio within a region of 1/2-2 and sintered at 1200℃.Moreover,the opacification of the glaze would change with the multiphase system and the transition of the microphase function caused by different B2O3 to P2O5 mole ratios.When the B2O3 to P2O5 mole ratio is 1：1,there is an in increase in the amount of high dispersion phase particles and droplets,and their size is close to that of visible light,thus strengthening the refraction and the scattering of the glaze,so that the whiteness of the glaze can be improved and reach 87.
