| description | A method for the production of closed edge filters suitable for filtering molten metal and filters made by such a method. The method comprises: providing a reticulated foam substrate having at least one first surface for forming a side face of the filter and two opposed second surfaces for forming the through-flow faces of the filter; applying a liquid comprising an organic coating component to the first surface; solidifying the organic coating component to form a filter precursor having a volatilizable coating on the first surface; impregnating the filter precursor with a slurry comprising particles of a refractory material, a binder and a liquid carrier; and drying and firing the impregnated filter precursor to form the filter having a closed edge. |
