摘要：

Octahedral monodimensional ferroelectrics are an important group of compounds due to their great number, the theoretical studies made on them, their property modulation by various ionic substitutions and their applications. They belong to different structural families: perovskites, tetragonal tungsten bronzes, LiNbO3… The Curie temperature is related to the chemical bond of these materials. Various aspects are described. They concern the influence of the size, the charge, the coordination, the electronic configuration of the cations, either in or out of the octahedron, the bond covalency and the degree of cationic order. © 1991, Taylor & Francis Group, LLC.
