Based on the results obtained for ceria nanocrystalline particles, the role of surface layers and the origin of anomalous lattice expansion in oxide nanoparticles are described in detail. The critical sizes and the anomalous dependence of lattice constants on particle size are discussed about ferroelectric and ferroelastic nanocrystallites. Consequently what are required for the research of oxide nanocrystallites in the near future are proposed.
