ABSTRACT:
A novel raw batch and improved fired refractory cement is described. A bulk refractory grain mass is initially bonded with a fired bond, which upon being fired includes Si.sub.3 N.sub.4 and/or Si.sub.2 ON.sub.2 reaction component that better protects the ultimate high temperature sintered cement product from erosion when the cement is used as a liner for furnace walls, troughs, and runners that contain a flow of molten iron or slag, as well as induction furnaces which process corrosive slag.
