FIELD: manufacture of ceramic articles.
SUBSTANCE: fiber-reinforced ceramic filter for filtering melt metal containing powder and fibers bonded with net of graphitized carbon. Method for making such filters comprises steps of impregnating foamed material with suspension containing ceramic powder, fibers and precursor of graphitized carbon containing binder; drying and firing without oxidizing agent at temperature 500 - 1000°C till partial or complete graphitization of carbon.
EFFECT: improved mechanical strength and rigidity of ceramic filter.
