【摘要】 以红土和氧化铁为原料,外加少量矿化剂,通过高能球磨活化工艺,采用固相法合成了硅铁红色料。研究了不同高能球磨活化时间对色料呈色的影响,对红土的化学成分进行了分析。结果表明:景德镇红土的主要化学成分为Si O2﹑Al2O3和Fe2O3,另外还有少量的K2O﹑Na2O和Ti O2。高能球磨活化工艺很好地促进了硅铁红色料的呈色,以红土93.7%﹑氧化铁6.3%,外加3%的硼砂作为矿化剂,高能球磨活化15 h所得色料呈色最佳,其色度值为:L*=38.21﹑a*=21.24﹑b*=11.87。更多还原

【Abstract】 Hematite silica red pigments were prepared via a solid state approach and a high energy ball milling technique using laterite and iron oxide as raw materials with a small amount of additional mineralizer. Effects of various high energy ball milling activation times on the coloration of the pigments were investigated. The chemical compositions of laterite were analysed. The results showed that Si O2, Al2O3 and Fe2O3 are the major chemical compositions of laterite from Jingdezhen area in addition to small amount of K2 O, Na2 O and Ti O2. High energy ball milling technique can greatly facilitate the color generation of hematite silica red pigments. Pigments present optimum coloration with laterite 93.7%, iron oxide 6.3% and additional 3% of borax and 15 h-high–energy–ball-milling activation. The chromatic values are: L*=38.21, a*=21.24, b*=11.87.更多还原
