Abstract
A ceramic filter having a porous structure with open alveoli, based on aluminum oxide or other highly refractory substances, particularly with a high content of alumina, is used to filter, respectively to purify molten metals of which the casting temperature is higher than 1000<o>C, particularly molten pig iron, during the casting in sand molds or chills. The flow speed through the filter is 200-5000 cm<3> of molten material per cm<2> of surface area of the filter per minute. The manufacturing of the ceramic filter usable as a disposable article is effected by means of a monoaluminum phosphate binder.
