    The invention relates to methods for the preparation of crystalline metallosilicates. A known method of producing crystalline metallosilicate by reacting a mixture of a solution of tetra propylammonium, sodium oxide, one of the metal compounds, for which aluminum or gallium is taken with the addition of silicon oxide l.
