FIELD: technological processes, filters.
SUBSTANCE: invention is related to the field of melt metal filtering. Precursor of ceramic material and ceramic filter made of it are proposed, comprising 35-70 wt % of fire resistant aluminium silicate; 10-30 wt % of colloid silicon dioxide; up to 2 wt % of modified bentonite; up to 35 wt % of carbon white. Precursor also contains water and possibly cellulating agent up to 10 wt % in the form of hollow spheres. Method for melt cast iron filtering is also described.
EFFECT: invention provides for production of strong foamed filter based on mullite and having improved characteristics in cast iron filtration.
