Abstract
A ceramic sponge made from plastic is described. Because of the ease of cutting the plastic in various shapes before converting to ceramic several unique applications are possible. In case of a column packing better contact between liquid and gas is made. For an auto catalytic converter better contact between gas and catalyst is realized. By cutting in other ways a filter to remove solids is made, permitting longer use before clogging, also a scrubber to remove particulates. A rotary ceramic filter is described; it is also a composite of fibers and ceramic which retains small particulates without excessive pressure drop upon passage of fluid through the filter. An acid resistant collector plate for an electrostatic precipitation is described.
