<p><P>PROBLEM TO BE SOLVED: To provide a manufacturing method of a ceramic filter which can form a filter membrane with uniform membrane thickness across the entire length of the ceramic filter. <P>SOLUTION: This manufacturing method is to manufacture the ceramic filter with the filter membrane formed on the inner wall surface of each through hole 3 of a long porous support 4 having one or more through holes 3 reaching from one end surface 1 to the other end surface 2, both being opposed to each other. The porous support 4 is set sideways inside a vacuum chamber 10 and the outer peripheral surface 5 of the porous support 4 is vacuum-sucked while feeding a membrane-forming slurry into each through hole 3 from one end surface 1 to the other end surface 2. Thus, the membrane is formed by stacking a membrane forming substance contained in the membrane forming slurry on the inner wall surface of each through hole 3, and thereafter, draining, drying and calcining the surplus slurry. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
