摘要: Provided is a method of manufacturing porous ceramic bodies with gradient of porosity, in which a gradient that is continuous to a pore size and porosity is precisely controlled in a simple way. The method includes the steps of: obtaining molded bodies by pressurizing and molding a mixture of powder obtained by mixing ceramic powder and polymer powder at a weight ratio of 1:1 to 100:1; and obtaining sintered bodies with gradient of porosity by sintering the molded bodies while applying a gradient pressure to the molded bodies.
