Abstract: The invention provides a method for producing sheet-like particles of zeolite that cannot be obtained by a top-down method, and provides sheet-like particles of zeolite having an 8-membered oxygen ring structure obtained by the method. A thickness of the sheet-like particles is 1 nm to 100 nm, and an aspect ratio (maximum width/thickness in particles) of the sheet-like particles is 100 or more.

Abstract: Aluminosilicates in the form of P type zeolites are used as detergency builders and have a silicon to aluminium ratio not greater than 1.33, preferably above 0.9. These zeolites will usually have a calcium binding capacity of at least 150 mg CaO per gram of anhydrous aluminosilicate. A preferred form of the zeolite P has a silicon to aluminium ratio up to 1.15, and preferably above 0.9, with a tetragonally distorted cubic crystal structure. A process of the preparation of these zeolite P builders is described.

Abstract: A process for the production of synthetic zeolite with the crystal structure of faujasite and with a composition corresponding to the formula:Na.sub.2 O . Al.sub.2 O.sub.3 . (2.5 .+-. 0.5) SiO.sub.2 . n H.sub.2 O(n = 0 to 8)comprising forming a reaction mixture containing Na.sub.2 O, Al.sub.2 O.sub.3, SiO.sub.2 and H.sub.2 O at a temperature of about 60.degree. to 105.degree. C in the presence of about 1 to 20% of finely divided zeolite A based on the weight of Na.sub.2 O + Al.sub.2 O.sub.3 + SiO.sub.2, thereby to form a precipitate which crystallizes to form a synthetic zeolite of faujasite structure. Advantageously the molar ratios of the oxides in the reaction mixture, exclusive of the added zeolite A, are approximately:SiO.sub.2 /Al.sub.2 O.sub.3 = 3 to 5Na.sub.2 O/SiO.sub.2 = 1.2 to 1.5H.sub.2 O/Na.sub.2 O = 35 to 45.Even if the mass is stirred during crystallization, little or no phillipsite is produced.
