摘　　要：以长石、石英、方解石、滑石和Ca_3（PO_4）_2为主要原料,以铁矿渣代替传统着色剂,在1250℃下,通过改变铁矿渣加入量制备出了具有多种色彩效果的分相花釉。利用X射线衍射仪、扫描电子显微镜结合能谱分析和拉曼光谱分析,研究了不同铁矿渣加入量对釉面性能及显微结构的影响,并对其呈色机理进行了研究。结果表明：铁矿渣加入量在10wt%～35wt%时,可以得到釉色及釉面花纹较好的分相花釉,并随着铁矿渣加入量的增多,釉面蓝色调加深,且釉熔体中孤立球状分相结构变小。当铁矿渣加入量达到40wt%时,釉面呈现深棕色,并带有金属光泽,其显微结构显示孤立球状分相密集处产生了连通状分相结构,并伴随赤铁矿析出。The separative-phase fancy glaze was successfully prepared with feldspar,quartz,calcite,talc and Ca_3（ PO_3）_2as raw materials and the iron ore residue was used as ceramic colorant for glazes instead of traditional colorant. At 1250 ℃,addition of different iron ore residue content developed a variety of glaze colors. The effects of iron ore residue contents on the surface appearance and microstructure of the glazes were studied by X-ray diffraction,scanning electron microscopy,energy dispersive spectrometry and Raman spectrum. The coloring mechanism of separative-phase fancy glaze from iron ore residue was also analyzed. The results indicate that the glazes with better surface appearance and color can be obtained when the iron ore residue content is 10wt%-35wt%. Moreover,the average diameter of the phase separation droplets decreases,so that the blue hue is darker with the increase of iron ore residue content. When iron ore residue content is 40wt%,the glaze shows dark brown with metallic gloss,and microstructure analysis showed that,together with the precipitation of hematite phase,the interconnected phase formed imbeding a dense discrete droplet phase.
