FIELD : chemistry. SUBSTANCE : method involves formation of an aluminosilicate initiator which exhibits Tyndall effect. The initiator is mixed with a transparent aqueous solution containing chemically active sources of Al, Si, M and R, where M is an alkali or alkali-earth metal, and R is an organic ammonium compound. The obtained reaction mixture reacts at temperature and time interval which are sufficient for obtaining a zeolite with average crystal size less than 500 nm. EFFECT : synthesis of different zeolites with nano-sized crystals. 9 cl
