| 内容： | A ceramic filter and method for preparing the same. The method for preparing the ceramic filter according to the present invention is characterized in comprising the steps of: (a) coating firstly a ceramic green paper prepared by using a slurry solution comprising ceramic fiber of 0.1-10 length, with an aluminum silicate solution and drying the firstly coated paper; (b) coating secondly the dried ceramic green paper with an aluminum phosphate solution and drying the secondly coated paper; and (c) calcining the dried ceramic green paper obtained from the step (b). The ceramic filter according to the present invention has excellent mechanical strength since the bonding strength between ceramic fibers is very high, and shows good porosity, gas permeability, and efficiency for capturing microparticles since the pores between the ceramic fibers are less blocked, and thus can be very usefully applied to gas exhaustion system for automobile. |
