纳米氧化铁调控钧瓷釉层显微结构及呈色分析
Microstructure and Color Analysis of Jun Porcelain Glaze Layer Regulated by Nano Iron Oxide
摘要
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.关键词
