Patent abstract
An improved particulate filtration system has an inlet, for the fluid to be filtered, connected to a housing containing a filter medium such that the fluid passes through the filter medium, and an outlet for the filtered fluid to exit. The filtration system's improvement is the filter medium being comprised of a porous ceramic of fused platelet grains. In a particular embodiment, the porous ceramic is a celsian porous ceramic, where the celsian grains have a hexagonal morphology and display a continuous volume thermal expansion coefficient from 100° C. to 1000° C.
