    摘要: Process for manufacturing an alkali metal aluminosilicate of zeolite wherein zeolite P seeds are produced in situ in a first reacting gel with a SiO2/Al2O3 ratio of above 2.2 and it is only after the formation of zeolite P seeds, but before said seeds have the time to fully grow, that sodium aluminate solution is added in order to get a gel which can have a SiO2/Al2O3 ratio of about 2 which therefore enables producing a zeolite P having also a SiO2/Al2O3 ratio of about 2.
