以化学试剂及工业原料配料，借助化学分析和X 射线衍射探讨了不同SM对高镁熟料中MgO 固溶的影响。通过采用EDS 分析高镁熟料中MgO 在各矿物中的分布情况。用光学显微镜分析了熟料的岩相结构，并测试了熟料的强度。结果表明，在熟料中固定MgO 为5％时，随着SM 值的增大，熟料中f-MgO 含量呈现一个明显的增大过程。MgO 在液相中的固溶率远远大于硅酸盐相中的固溶率。熟料中固溶的MgO 主要受中间相的影响，MgO 更趋向于在液相中固溶。且随着SM 值的增大，熟料中A 矿含量增多，A 矿晶形发育逐渐完全，边棱均比较光洁，包裹物数量减少。硅酸盐相明显增多，中间相减少。熟料的3 天抗折强度基本上不随SM 变化而变化，而3 天抗压强度受影响比较大，随SM 增大而增大。
