The perovskite complex oxides have a series of special performance, and the successful preparation of nano-building blocks is the key to a wide range of application for this kind of materials. In this article, the structure of the perovskite complex oxides is introduced in detail. The characteristics and the existent problems of each kind of preparation technology are discussed for this type of nano-building blocks, and based on the existing research in the do- mestic and foreign countries, the performance and application of nano-building blocks oxides of this type are summarized in magnetism, gas sensitive effect, catalysis, high-temperature superconductivity, and so on. Finally the forecast for the development of the nano-building block of perovskite complex oxides is made.
