Title:
METHOD FOR PRODUCING POROUS MATERIAL
Document Type and Number:
Japanese Patent JP3391155
Kind Code:
B2
Abstract:
PURPOSE: To provide a method for producing the porous material excellent in crystallinity and heat resistance and not containing impurities.
CONSTITUTION: The method for producing the porous material comprises the first process for dispersing a silicon-containing substance in an aqueous solution containing a surfactant and changing the pH of the dispersion to ≥10, the second process for changing the pH and temperature of the dispersion to <10 and ≥500°C, respectively, to form the composite product of silicon oxide with the surfactant, and the third process for removing the surfactant from the composite product.
