An overview of recent studies on the perovskite oxides is presented, especially those on the novel perovskite oxides which were characterized by its special crystal structure and electronic structure. The basic principles and characteristic rules were analyzed from the aspect of its basic structure. As for their application in solid fuel cell, oxygen-permeating membranes, gas sensor, magnetic refrigeration, oxidation and reduction catalyst, the status and the trend of development of perovskite-type oxides were described, and their advantages as well as problems to be solved were also pointed out. In addition, a number of experimental methods of intercross subjects, which were used to find out the morphological and surface properties of the perovskite materials, are introduced,too.
