Abstract
Making denser ceramic sinters by carrying out the sintering operation at elevated temperatures and in 100% oxygen at a pressure of at least 1.5 atmospheres, and then cooling the sinter without control of the ambient atmosphere. The product has a bulk density of at least 98% of the theoretical density of the sinter.
