摘要
用x射线衍射的近似函数法测定了在不同温度下煅烧菱镁矿获得氧化镁(MgO)晶粒大小和晶格畸变,并测量了水化速率。结果指出,MgO的晶粒大小和晶格畸变是其水化活性的根本原因,即晶粒越细,晶格畸变越大,则水化活性越强。
The crystalline size and Lattice distortion of MgO obtained by calcinated magne- site at different temperatures have been determined with approximate function method of XRD and so has the rate of hydration. The results show that the crystalline size and lattice distortion of MgO are the fundamen- tal cause of the activity of hydration. The smaller the crystalline size, and the greater the lat- tice distortion, the higher the hydration activity.
