1. A method of making a filter, the method comprising:
pumping a liquid preceramic polymer through an interior of a porous support, the liquid preceramic polymer comprising a preceramic polymer in an organic solvent, the preceramic polymer comprising, circulating the liquid preceramic polymer through the porous support until the liquid preceramic polymer permeates a channel in the porous support and passes from the interior of the porous support to an outer surface of the porous support, forming a permeated porous support; and
pyrolyzing the permeated porous support to yield a porous ceramic membrane layer on a surface of the channel of the porous support.
