常见氧化物对C_(11)A_7·CaF_2稳定性的影响

A Research on the Performance of Common Oxides on the Stability of C_(11) A_7·CaF_2

研究了常见氧化物在高温下对Ｃ１１Ａ７·ＣａＦ２ 稳定性的影响．结果表明：ＭｇＯ、Ｋ２ Ｏ、Ｎａ２Ｏ 和Ｐ２ Ｏ５ 对Ｃ１１ Ａ７·ＣａＦ２ 的稳定性没有影响；ＣａＯ 在高温下可与Ｃ１１ Ａ７·ＣａＦ２ 发生反应，使其转化为Ｃ３Ａ，但在硅酸盐水泥熟料的正常煅烧制度下，转化率较低，不是导致水泥熟料中Ｃ１１ Ａ７·ＣａＦ２ 转变为Ｃ３ Ａ的主要原因．

According to our findings,we are to talk in this essay about the performance of common oxides on the stability of C 11 A 7·CaF 2.We find that MgO,K 2O,Na 2O or P 2O 5 will not decompose C 11 A 7·CaF 2 at a high temperature while CaO can react on C 11 A 7·CaF 2 and turn it into C 3A.This is,however,not the main factor to cause C 11 A 7·CaF 2 to change to C 3A in the cement clinker.
