FIELD: chemistry.
SUBSTANCE: elaborated is method of various molecular sieves synthesis. Method includes formation of reaction mixture, which includes reaction-able sources of frame elements plus, at least, one template agent, interaction of mixture to, at least, partial crystallisation of molecular sieves and creation of suspension of crystal germs and addition to them of raw material (sources) of frame elements, for instance, aluminium and silicon for crystal germ growth. Rate of adding raw material components is regulated in such way that it is in fact the same as the rate of crystal growth, and nucleation of new crystals is in fact absent. Crystal germs can be the same or different from added raw material components, which allows to obtain foliated molecular sieves. When crystal size reaches desirable value, they are isolated by common methods.
EFFECT: method ensures growth of crystals from crystal germs without nucleation of new crystals.
