Abstract
A highly densified chromium oxide-based sintered body is produced by heating a powder mixture of chromium sesquioxide and at least one substance selected from silica, zirconia and zircon in a carbon powder. The highly densified chromium oxide-based sintered body has excellent resistance to corrosion and excellent heat shock resistance, and thus is useful as a refractory material.
