ABSTRACT:
A composition blending carbon with powdered chromium oxide in an alumina or aluminum silicate matrix, including silicon metal powder to inhibit carbon oxidation, is more advantageous in resisting molten iron and slags than refractories based on carbon or chrome additions not combined. The resultant refractory mixes are suitable for all conventional application methods.
