摘　　要：探讨了微波辅助干燥工艺在sol-gel法制备硅铁红陶瓷颜料中的作用。研究结果表明,Fe2O3/SiO2的最佳合成条件为:硅/铁摩尔比为7∶1,微波辐射功率和时间分别为75%和8 min,前驱体煅烧温度和时间分别为750℃和2 h;此条件制备的Fe2O3/SiO2,其包裹率达到93.1%。The role of the microwave-assisted drying technique on the sol-gel synthesis of Fe203/SiO2 ceramic pigment was studied in this paper. The optimal parameters for the synthesis of Fe2OJSiO2 are listed as follows, the mol ratio of Fe/Si is 7 ： 1, then microwave radiated for 8 min with a power of 75 %, subsequently, sintered at 750 ℃ for 2 h to obtain Fe,Oo/SiO, ceramic pigment. The results indicate, the encapsulation rate of Fe.OjSiO. can reach 93.1%.
