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.
