摘　　要：以钙系生料釉为基础,引入结晶剂CuO、MnO2制备无铅CuO-MnO2系金属光泽釉;结合XRD、SEM-EDS进行物相组成定性分析和显微结构表征,系统探究外加TiO2、V2O5以及玻璃粉对金属光泽釉釉面分相的影响。研究表明:一定量的TiO2、V2O5引入能有效促进釉面的分相,将玻璃粉部分替换基础釉中的钾长石能使得釉熔体的高温粘度降低,并进一步加剧釉面分相,促进CuMn2O4铜锰尖晶石在釉层表面的析出和富集;当TiO2引入量为2%,V2O5引入量为1%,玻璃粉引入量为25%(同为质量分数)时,金属光泽釉釉面效果最佳。The lead-free CuO-MnO2 system metallic luster glaze was prepared by adding crystallizer CuO and MnO2 based on calcium raw glaze.The phase composition and microstructure were characterized by XRD and SEM-EDS,and the influences of adding TiO2,V2O5 and glass powder on the phase separation of metallic luster glaze were systematically investigated.The results show that a certain amount of TiO2 and V2O5 effectively promotes the phase separation of the glaze.The high temperature viscosity of the glaze melt is reduced by partially replacing the potassium feldspar in the base glaze with glass powder,further aggravates the glaze phase separation,promotes the precipitation and enrichment of CuMn2O4 copper manganese spinel on the glaze surface.When the amount of TiO2 is 2%,V2O 5is 1%,and the amount of glass powder is 25%(both are mass fraction),the effect of glossy glaze is the best.
