PROCESS FOR PREPARING POWDERY 4A TYPE ZEOLITE Russian patent published in 1994 - IPC

Abstract RU 2005692 C1

FIELD: inorganic chemistry. SUBSTANCE: a diluted solution of sodium silicate is atomized by a nozzle at 70-80 C and added to a dilute clear mother liquor derived from the production of Al(OH)₃ by the Buyer process. The spontaneously precipitated material in the mother liquor at 70-80 C is subjected to the ripening process until a finely crystalline powdery 4A type zeolite is formed having a granulometric composition in which d₅₀ is not greater than 3 micros. EFFECT: improved properties of the zeolite.
