  • Synthesis method of spherical hollow aluminosilicate cluster
    Patent number: 6254845
    Abstract: The present invention provides a method for the homogenous and highly efficient synthesis of an aluminosilicate material that can be used for adsorbents, deodorants, catalyst carriers, humidity adjustors, and the like, and relates to a method for manufacturing spherical hollow silicate clusters, comprising steps of mixing a solution of a silicon compound and a solution of an aluminum compound or transition metal compound, each with a solution concentration of 10-1000 mmol, rapidly or simultaneously at a rate of 1-10,000 mL/min, removing a salt formed as a by-product, and then subjecting the mixture to hydrothermal synthesis to yield the silicate clusters.
