摘要：

以不同的硅源分别合成了L型沸石,考察了影响L型沸石晶化相区的各种因素。首次发现了L型沸石导向刑,并对其导向作用进行了研究。

Abstract:

Not only was L-type zeolite synthesized by using silica sol and a kind of amorphous silica, but also by more cheep water glass. The influences of various parameters on the crystallization field of L-type zeolite were investigated. We also found the directing agent of L-type zeolite, which is a state of sol. We applied electron diffraction technique to investigate and detect the nuclei with L-type zeolite structure in the colloidal system of the directing agent. Directing agent of L-type zeolite was Largely able to accelerate the crystallization rate of L-type zeolite and to enlarge crystallization field of L-type zeolite. Experimental results showed that directing agent of L-type zeolite had practical value to the production of L-type zeolite.
