中文摘要：

在钧瓷基釉中分别加入不同比例的铜、氧化铜、硝酸铜,采用相同的烧结气氛和烧结时间进行釉烧,研究在相同的气氛下以不同的铜元素存在形式和添加量对钧瓷釉层显微组织和釉层呈色的影响。借助X-射线粉末衍射（X-ray diffraction,XRD）、扫描电子显微镜（Scanning electron microscope,SEM）和X-射线电子能谱仪（Energy dispersive X-ray,EDX）等检测手段,系统研究了铜元素不同存在形式对钧釉烧样品的显微形貌及分相等的影响;通过紫外可见漫反射光谱仪（Diffuse reflectance ultraviolet visible spectrometer,DRUVS）和分光测色仪（Spectrophotometer,SPM）分析铜元素及其含量对钧瓷釉层呈色的影响。结果表明添加相同含量的铜元素,釉层呈色基本相同,相对而言,以硝酸铜作为添加剂的钧瓷试片釉层表面无明显气泡且呈色更均匀。

英文摘要：

The sample with addition of copper,copper oxide and cupric nitrate in matrix glaze,respectively,was glaze-sintered under the same sintering atmosphere and time.Effects of different material-forms and contents of copper element on the coloring and microstructure of Jun porcelain were studied.By use of x-ray diffraction,scanning electron microscope and energy dispersive x-ray,we systematically investigated the effects of different material-form of copper element on the microstructure and phase separation of the Jun porcelain.With the help of diffuse reflectance ultraviolet visible spectrometer and spectrophotometer,the effects of different material-form of copper element and content on the coloring of the Jun porcelain were analyzed.The results showed that the coloring of the glaze layer was basically identical under the same content of copper element.Relatively speaking,the Jun-porcelain samples with cupric nitrate as addition were more homogeneous coloring and less-porosity.
