POROUS SINTERED MATERIAL, FABRICATION METHOD THEREOF AND A FILTER COMPRISING THE SAME

摘要

PURPOSE: A porous sintered body, a manufacturing method thereof, and a filter including the same are provided to offer good usability in component and filter etc used for gas and various kinds of fluids with a big specific surface area and dimension precision. CONSTITUTION: A porous sintered body includes a metal sintered body in which macropores are formed and metal hydroxide in which opened pores of nano size are formed on the surface of the metal sintered body. The metal includes one component selected from a group consisting of Al, Ti, Mg and alloy which is formed by alloying other metals. The porosity of the porous sintered boy is 10 - 90%.
