摘要/Abstract

摘要： 本文在钧瓷釉中添加不同质量分数的纳米氧化铁,分析在还原气氛(96%Ar/4%H₂)与氧化气氛(空气)烧制后钧瓷呈色及釉面显微结构的变化,采用分光测色计研究了颜色变化,利用X射线衍射仪、拉曼光谱仪研究了钧瓷物相成分,利用扫描电子显微镜研究了釉层微观结构。结果表明:随着纳米氧化铁含量梯度增加,还原气氛下钧瓷试片从淡青色变为蓝色再变为青灰色,氧化气氛下从白色变为黄色再变为酱黑色。当釉层中纳米氧化铁含量达到3.0%(质量分数)时,釉面SiO₂晶相完全消失,呈非晶态。随着纳米氧化铁含量的增加,釉面呈液-液分相结构,还原气氛下显微结构尺寸从85 nm增加至150 nm,且Fe²⁺相对含量上升。氧化气氛下,当釉面达到玻璃化后,分相结构尺寸从217 nm增加到307 nm。

Abstract: Different mass fractions of nano iron oxide were added to Jun porcelain glaze, and analyzed changes in the color and microstructure of Jun porcelain after firing in reducing atmosphere (96%Ar/4%H₂) and oxidizing atmosphere (air). The color change was studied by spectrophotometer, the phase composition of Jun porcelain was studied by X-ray diffractometer and Raman spectrometer, and microstructure of glaze layer was studied by SEM. The results show that with an increase in the gradient of nano iron oxide content, Jun porcelain specimens changes from light blue to blue, then to cyan gray under reducing atmosphere, and from white to yellow, and then to sauce black under oxidizing atmosphere. When nano iron oxide content in the glaze layer reaches 3.0% (mass fraction), the SiO₂ crystal phase on the glaze completely disappeares and the glaze appeares amorphous. With the increase of nano iron oxide content, the glaze exhibites a liquid-liquid phase separation structure, and the microstructure size of reducing atmosphere increases from 85 nm to 150 nm, with a relative increase in Fe²⁺ content. After the glaze of Jun porcelain reaches glass transition in an oxidizing atmosphere, the size of the phase separation structure increased from 217 nm to 307 nm.

Key words: Jun porcelain, nano iron oxide, microstructure, structural color, glaze layer, chromogenic analysis
