摘　　要：综述了水泥工业处置废弃物过程中常见的几种重金属元素(Cr、Cu、Zn、Pb、Cd)在水泥熟料矿物中的固溶机理。一些重金属离子更容易固溶进入硅酸盐矿物,一些重金属离子更容易固溶进入中间相矿物,并因固溶量的不同而稳定不同的矿物晶型,超过极限固溶量时形成新的矿物。重金属离子在水泥熟料矿物相中的固溶方式和极限固溶量都与其矿物相的晶体结构有关。应进行深入研究,以便于水泥工业无害化利用产业废弃物。This paper summarizes solidification mechanisms of several common heavy metals（ Cr,Cu,Zn,Pb,Cd） in the waste co-processing technology of cement industry. Some heavy metal ions may more easily combine into silicate minerals by solid solution; others more likely into mesomorphic phase minerals. Meanwhile,different stable mineral crystals come into being as different solid-soluted content of heavy metals,and new minerals form when in excess of solid solution limits. Solid solution ways and solid solution limits of heavy metal ions in cement clinker minerals have a close connection with the crystal structure of its mineral phase. Comprehensive analysis and thorough research may take full advantages of cement industry in industrial waste co-processing in the principles of hazard-free.
