摘　　要：就层状结晶硅酸钠的制备条件进行了探讨。发现采用KCl作为晶型转化剂,其加量为5%,在温度800℃下转化10min,δ晶型转化最完全,可以得到钙、镁离子交换量大的层状结晶硅酸钠。The preparation conditions of laminar sodium silicate were discussed. It is observed that KCl is the better catalyst. At the condition of 800℃ and 10 minutes, when 5 percent catalyst is added, δ crystal style conversion is most complete, and the high quality laminar crystal sodium silicate with large Ca and Mg ion eschange capacity can be obtained.
