钧瓷天蓝、天青釉色中氧化铁的呈色作用

氧化铁在钧瓷天蓝、天青系列釉色中的着色作用以及乳光蓝色问题,一直是学术界争论的焦点。本研究通过放大氧化铁含量的实验验证方法,通过SEM(scanning electron microscope-扫描电子显微镜)、EDS(Energy Dispersive Spectrometer-能谱仪)、XRD(X-ray diffraction-X射线衍射)等分析方法,重点研究了基础组成和分相结构对釉中氧化铁呈色的影响。同时,作者通过验证研究得出,钧瓷天蓝、天青系列釉色中,真正起呈色作用的是釉中的氧化铁等着色剂,第二相微粒散射呈色并非钧釉的普遍现象,或只是辅助呈色作用。

A Study of Iron Oxide Coloring Function in Blue Glaze & Green Glaze Jun Porcelains

There remain the focus of debates in academic circle as to the function of iron oxide in the blue glaze and green glaze Jun porcelains,and the generation of blue opalescence as well.In this paper,the research group conducts a test of its coloring process and mechanism by enlarging the content of iron oxide,especially analyzes the effects caused by the basic glaze components and the microstructure of liquid-phase separation upon iron oxide coloring with XRD,SEM,EDS,etc.The result indicates that it is iron oxide and other colorings that matter more than blue opalescence that occurs accidentally or just aids to the coloring process.
