摘　　要：采用纳米氧化铁作为着色剂,在还原气氛下调控釉烧温度条件,探究烧制温度对铁系钧瓷釉呈色与显微结构的影响。通过分光测色仪、X-射线粉末衍射仪、STA热分析仪、扫描电子显微镜等测试表征手段研究了釉烧温度改变对钧瓷釉面呈色及显微结构影响。结果表明:烧制温度由1260℃升高到1300℃时,釉面蓝色区域显著增加;烧制温度在1260~1300℃范围内,釉层表面具有明显的二氧化硅晶体衍射峰,而当烧制温度为1320℃时,二氧化硅晶相消失,釉面呈现玻璃态;伴随温度的升高,釉层表面分相液滴尺寸减小;钧瓷中心与边缘呈色差异可能是由于中心显微结构尺寸大于边缘显微结构尺寸。Using nanoiron oxide as a colorant,we controlled the glaze firing temperature conditions in a reducing atmosphere to investigate the effect of firing temperature on the color and microstructure of iron-based Jun porcelain glaze.The effect of changes in glaze firing temperature on the color and microstructure of Jun porcelain glaze was studied through various testing and characterization methods such as spectrophotometer,X-ray powder diffractometer,STA thermal analyzer,and scanning electron microscope.The results indicate that when the firing temperature increased from 1260℃to 1300℃,the blue area of the glaze significantly increased.Within the range from 1260℃to 1300℃,the glaze surface exhibited distinct peaks of silica crystal diffraction,but at 1320℃,the silica crystal phase disappeared,and the glaze surface turned glassy.With increasing temperature,the size of phase separation droplets on the glaze surface decreases.The color difference between the center and edge of Jun porcelain may be due to the larger size of the center microstructure compared to the edge microstructure.
