摘　　要：铝酸钙粉的结构会受到原料变化的强烈影响。对加入活化剂与未加入活化剂生产的铝酸钙粉进行了相关的结构鉴定与溶出率测定。X射线衍射及热重分析证实,加入活化剂的铝酸钙粉矿物相中含有卤化物,其中矿物相CaAl3XO7可能部分水解形成类弗雷德盐的双羟合结构体,这种铝酸钙粉存在2 116 cm-1及1 981 cm-1两个红外光谱特征峰。矿物相不同,铝酸钙粉的三氧化二铝溶出率有较大差异。The structure of calcium aluminate powder will be strongly affected by the changes of raw materials.The structure and dissolution rate of calcium aluminates,whieh were produced with activator and without activator,were identified and measured.XRD and TGA analysis showed that after adding activator,the mineral phase of calcium aluminate powder con- tained halide,in which the mineral phase CaA13XO7 may be partially hydrolyzed to form Ffiedel＇s salt double hydroxide phases.Furthermore, this calcium aluminate powder had two IR spectral feature peaks at 2 116 cm^-1 and 1 981 cm^-1.Different mineral phases, dissolution rates of Al2O3 in the calcium aluminate powder were quite different.
