METHOD OF MANUFACTURING GAS FILTER FOR MEMBRANE USING SOLVENT EXTRACTION OF AMORPHOUS COMPOSITE POWDER

摘要

Disclosed is a method for manufacturing a gas filter for a membrane using solvent extraction of amorphous composite powder. According to the present invention, the method for manufacturing the gas filter for the membrane comprises the steps of: (a) mixing the infusible and amorphous alloy hardening powder and sacrificial powder which is soluble in an acid solution, and forming amorphous composite powder; (b) forming a precursor from the amorphous composite powder using a spark plasma sintering method; and (c) inputting the precursor into the acid solution and selectively extracting the sacrificial particles from the precursor.
