Abstract:

It is an object of this invention to provide a method for reoxidizing partially-reduced ceramic. It is another object of this invention to provide a method for preventing cracking of a partially-reduced ceramic from stresses occurring during reoxidation. It is a further object of this invention to provide a method for reoxidizing ceramics which have been processed under reducing conditions. These and other objects are achieved by placing a partially-reduced ceramic in a chamber having a nonreactive atmosphere and then introducing an oxidizing gas into the chamber at a rate which is slow enough to prevent the ceramic from cracking.
