摘要：
Long-term isothermal grain growth kinetics of nanocrystalline SnO2 was investigated. A limiting grain size for each annealing temperature was observed and the grain growth behaviour can be described with a non-linear relaxation equation. Structural relaxation of the interfaces in nanostructure materials plays an important role in the grain growth process. (C) 2003 Acta Materialia Inc. Published by Elsevier Science Ltd.
