【摘要】 介绍Ｐ相、Ｑ相的组成，并对单矿物Ｐ相和Ｑ相的形成条件进行研究，研究少量Ｐ相和铁相对Ｑ相为主要矿物的水泥的烧成条件的影响。实验结果表明：掺加少量Ｐ相的Ｑ相－ＣＡ－Ｃ_１２Ａ_７水泥，烧成温度大大降低；铁相的存在，能够降低 Ｑ相的烧成温度，富镁能促进 Ｑ相的形成。更多还原

【Abstract】 The compositions of P. Q phase are introduced respectively. The formation of single phase of P and Q and the effeet of a small amount of P and tetracalcium aluminoferrite phase on sintering conditions of cement whose main mineral is Q phase are reserched. The results show that a small amount of P phase can remark ablely decrease the sintering temperature of Q phase,and the tetracalicum aluminoferrite can decrease its sin tering temperature. The rich - magnesia can accelerate the for mation of Q phase.更多还原
