【摘要】 采用X射线衍射法对粉煤灰和石灰石烧成熟料的物相组成进行了分析,对烧结过程铝和硅的反应行为进行了研究。通过在不同生料配方,不同烧结温度下熟料物相半定量分析表明,在生料配方C/A为1.9左右,温度在1320~1 360℃范围内,铝硅的反应产物主要是C12A7和γ-C2S,在此条件下,熟料中的Al2O3在碳酸钠溶液中能较好地溶出。在低于1260℃温度下的烧结熟料中没有C12A7生成。更多还原

【Abstract】 This paper is to study the reaction behavior of Al2O3 and SiO2 in the sintered powder,using XRD to analysis the phase composition of it.The results show that at different value of raw prescription and different sinter temperature,the main phases of the reaction production of Al2O3 and SiO2 are C12A7和γ-C2S,meanwhile in this phase it has the best leaching rate of Al2O3 dissolved in sodium carbonate.Below 1 260 ℃,there is no production of C12A7 in the sintered powder.更多还原
