Abstract:
There is provided a ceramic filter provided with a ceramic porous membrane having few defects, small and uniform membrane thickness, and high resolution performance. The ceramic filter includes: a porous substrate which is a microfiltration membrane (MF membrane), a titania UF membrane which is an ultrafiltration membrane (UF membrane) formed on the porous substrate and has an average pore size of 2 to 20 nm and an average thickness of 0.1 to 1.0 μm, and a silica membrane which is formed on the titania UF membrane and a ceramic porous membrane a part of which has penetrated into pores of the titania UF membrane or into pores of the UF membrane and the porous substrate.
