Porous ceramics (ceramic filter elements)
Porous filter ceramics (also known as ceramic foam filters) are used for cleaning liquids or gases when passed through the filter material.
They are manufactured as follows: organic compounds are added to the Pythagoras mass and are then burnt out during sintering so that a porous structure is formed. The basic properties of ceramic foam filters are their filtration properties and gas permeability, which are defined by means of the size, number and type of pores. It is clear that the differing permeabilities of filter elements are dependent upon the number and composition of the organic components. Furthermore, the size of the pores and their number are influenced by the pressure applied during pressing as well as by the sintering temperature.
Products in porous ceramics are increasingly used for the manufacturing of filter elements and membranes for electrolytic vats and filters for oxygen plants. They are utilized as catalyser holders in catalytic processes, mounted on filter presses for filtering suspensions and in foundry operations for separating solid material inclusions from the molten metal.
Ceramic filter elements have two crucial properties for the consumer:
