METHOD OF MANUFACTURING ARTIFICIAL ZEOLITE AND METHOD OF MANUFACTURING FOAMED PERLITE

摘要

PROBLEM TO BE SOLVED: To provide a novel manufacturing method, in which the deterioration of zeolite manufacturing rate or a gelating phenomenon due to the concentration of silicate ion is prevented in a manufacturing process of an artificial zeolite. SOLUTION: The artificial zeolite is manufactured by mixing a sodium hydroxide aqueous solution and activated Al2O3 with perlite to form a slurry and treating the slurry in an autoclave.
