The present invention provides a manufacturing method of a ceramic filter containing nano pores which enables to effectively manufacture the ceramic filter having the uniform nano-sized pores, and excellent filterability and durability by using micro-sized salt powder, wherein the manufacturing method comprises the steps of: preparing and mixing an aluminum oxide powder and a nano-sized salt powder as main materials; adding a coating agent to the mixed powder of the aluminum oxide powder and the nano-sized salt powder and coating the mixed powder to obtain a dough; positioning the dough in a forming mold, pressing the dough, and molding the same to form a uniform molded product; sintering the molded product at 1500~2000°C to remove the coating agent which is coated on the molded product; and immersing the sintered molded product in water and washing the molded product to remove the nano-sized salt powder. |
