Abstract
A monolithic refractory honeycomb filter of zircon or zircon plus an oxide additive is useful to remove impurities from molten metal, particularly from molten steel. The filter has a frontal contact surface containing the openings of a plurality of through-and-through cells for passage of the molten metal. Impurities adhere to the frontal contact surface of the filter and to the cell walls themselves.
