摘要
以SiO2为包裹相,Fe2O3为发色剂,采用固相法制备了硅铁红陶瓷颜料。考察了SiO2/Fe2O3质量比、铁源、煅烧温度、矿化剂以及助色剂等对色料的影响。采用XRD仪、扫描电镜和色度测量仪等分析手段对色料进行了表征。结果表明:SiO2/Fe2O3=85/15(质量比)时色料红度值最大,煅烧温度1100℃最佳,以硝酸铁制备的色料红度值达到22.31,以加入3%的复合矿化剂Na2SiF6:LiF=2∶1(质量比)效果最好,不同的助色剂对色料的影响不同,其中以La(NO3)3为助色剂的效果最好。
Silicon-iron-peach ceramic pigment was fabricated by solid-phase method,using SiO2 and Fe2O3 as raw materials.The influence of SiO2/Fe2O3 mass ratio,Fe2O3 sources,calcining temperatures,mineralizers and coloring aids on the color of the obtained pigments were systematically investigated.The as-prepared samples were characterized by XRD,colorimeter and SEM.Experimental results show that the red a-value is 12.51,when the SiO2：Fe2O3（mass ratio） was 85：15.The optimum firing temperature was 1100℃.The red a-value is 22.31 with Fe（NO3）3.9H2O as the source of Fe2O3.The mixture of Na2SiF6 and LiF to the mass ratio of 2：1 is the most effective mineralizer.La（NO3）3 is more beneficial to improving the red a-value of the pigments.
