发布时间：2019-01-05 21:04
【摘要】：成功地制备了一种适用炻质瓷装饰的大红釉。该釉以包裹型镉硒红色料为着色剂 ,基釉为长石石灰混合生料釉 ,氧化气氛下烧成。新的釉料完全无镉溶出 ,不含铅、铋、钡、锌、锑、铜等对人体有害的元素 ,符合当前陶瓷装饰必须无公害的新理念。用SEM ,EPMA ,OM ,XRD等对釉进行了显微结构观察、定性与成分分析 ,研究了其显色机理。对釉的主要性能如分光反射率、热膨胀系数、显微硬度、熔融温度、铅镉溶出量等进行了测试。结果表明 :釉的物相组成主要是玻璃相、残余石英及ZrSiO4 Cd(SxSe1 -x)色料 ;该釉是未熔融的包裹型色料晶体呈色 ,色料在釉中均匀分布 ;坯釉中间层发育良好 ,有莫来石、钙长石类晶体析出。其成熟温度为 115 0～ 12 0 0℃ ,呈色纯正 ,鲜艳明快 ,不流不裂 ,釉面硬度高 ,耐化学腐蚀性好 ,铅、镉溶出量完全达到ISO 64 862 :1999(E)新规定。
[Abstract]:A red glaze suitable for stoneware decoration was successfully prepared. The glaze was coated with cadmium and selenium as coloring agent and base glaze as feldspar lime mixed raw glaze. The glaze was sintered in oxidized atmosphere. The new glaze is completely cadmium free, free of lead, bismuth, barium, zinc, antimony, copper and other harmful elements. The microstructure, qualitative and component analysis of glaze were observed by SEM, EPMA, OM, XRD et al. The color mechanism of glaze was studied. The main properties of glaze, such as reflectance, coefficient of thermal expansion, microhardness, melting temperature, lead and cadmium dissolution, were tested. The results show that the phase composition of the glaze is mainly glass phase, residual quartz and ZrSiO4 Cd (SxSe1 x) color, and the glaze is an unmelted encapsulated pigment with uniform distribution in the glaze. The intermediate layer of glaze is well developed with mullite and calcium feldspar crystals. The ripening temperature is 115.0 ~ 1200 鈩，
