摘　　要：采用化学试剂配成不同SiO2含量的原料,高温烧结,制成试样,对其进行观察,分析SiO2成份对烧结矿矿相组成的影响。实验结果表明,随着SiO2含量减少,碱度增加,铁酸钙和氧化亚铁的含量也随着增加,磁铁矿含量相应减少;烧结样的气孔率变小,气孔趋于不均匀分布。当SiO2的含量很高时,相应出现硅酸盐相。The purpose of the experiment was to analyze the effect of SiO2 on composition of the sinter mineral phase, when the content of SiO2 was different. During the experiment, the chemical reagent was mixed with the different content of SiO2, and sintered at high temperature. Then, the sample of the sinter was analyzed by chemistry and microstructure. The result showed that with the SiO2 decreasing, the content of calcium ferrite and FeO increased; contrarily, magnetite decreased; when the content of SiO2 was higher, the silicate was engendered.
