Effect of oxygen release on the sintering of fine CeO2 powder at low temperature

The sintering behavior of fine and coarse ceria (CeO2) powders was examined by monitoring the continuous shrinkage of a compact body from 30 to 1700 degreesC in air. The accelerated sintering behavior of a fine powder was related with oxygen release from CeO2 at 700-800 degreesC and > 1600 degreesC. (C) 2003 Acta Materialia Inc. Published by Elsevier Ltd.
