This review provides general description and definition as well as basic in
formation on the synthesis and structure of zeolite molecular sieves. Forma
tion of zeolite structures starting from primary and secondary building uni
ts is dealt with. Principles of mechanisms of zeolite synthesis, function o
f organic templates in the synthesis, and possibilities of isomorphous subs
titution into the siliceous framework are outlined. New trends in the zeoli
te synthesis are mentioned. A review with 69 references.
