Abstract
Synthetic mazzite having a small particle size is advantageously prepared by making present a transparent liquid phase compound in a starting mixture containing a silica source, an alumina source, an alkali source and a tetramethylammonium source. The transparent liquid phase compound is obtained by mixing an aqueous solutuion of an alkali metal silicate, an aqueous solution of an alkali metal aluminate, an aqueous solution of an alkali metal hydroxide and a tetramethylammonium compound and aging the mixture.
