Abstract
A method of manufacturing a molten metal-resisting ceramic fiber composition includes mixing ceramic fibers, a frit, ceramic additives, a low temperature binder, and water. The mixture is formed into a desired shape, preferably by being extruded through a die. The shaped mixture is baked at low temperature, and then is fired at high temperature. During firing, the low temperature binder is oxidized and the frit is melted so as to substantially coat the fibers and fuse them into a porous matrix.
