Abstract: The preparation, structure and properties of ferroelectric nanometer sized powders, nanocomposites, and nanoceramics were introduced. The change of structure and properties caused by the reduction
of particle size and pertinent mechanisms were discussed. Transparent nanocomposites were expected to be applied as the optical memories, optical computer, etc devices, while the nanoceramics can be
widely used to improve the characteristic parameters of current capacitors due to the greatly enhanced dielectric permittivity, breakdown voltage, ageing-resistivity, mechanical strength, etc. Better quality
of devices will be obtained by using the nanosized powders.

Key words: ferroelectrics, nanopowder, nanoceramic, nanocomposite, size effect, dielectric properties
