摘要
利用本地高岭土和含铁质的红泥,添加少量氧化铁、氧化铬、碳酸钴等过渡金属化合物,在高温氧化气氛下进行Fe-Cr-Co系黑釉试制,结果表明:红泥20％,高岭土 14％,石英16％,钾长石27％,方解石5.8％,滑石6.5％,Fe203 5.7％,Cr2O3 2.3％,CoCO3 2.62％,此时黑釉的色度和光泽度最好,白度最低为1.7％,光泽度可达15.7％.所制备的黑釉中绝大部分硅酸盐矿物都转化成了玻璃相组织,釉层形成过程中未见明显析晶,黑色的呈现主要是Fe3+、Cr3+和Co2+三种离子在可见光下光学效果的叠加所致.
Abstract
Fe-Cr-Co system black glaze was trial-produced by using local kaolin and red mud containing iron and adding a small amount of transition metal compounds such as iron oxide,chromium oxide and cobalt carbonate under high-temperature oxidation atmosphere.The results showed that:red mud 20％,kaolin 14％,quartz 16％,potassium feldspar 27％,calcite 5.8％,talc 6.5％,Fe2O3 5.7％,Cr2O3 2.3％,and CoCO32.62％.At this time,the black glaze color and glossiness are the best,whiteness is the lowest 1.7％,gloss can reach 15.7％.The majority of the silicate minerals in the prepared black glaze transformed into glass phase structure,and no obvious crystallization was observed during the formation of the glaze layer.The black appearance was mainly caused by the superposition of the optical effects of Fe3+,Cr3+and Co2+ions under visible light.
