| The ferroelectric ceramics oxides, whose prototype is BaTiO3, have seen an increased attention because the demands for smaller and speedy electronic devices. There are several processing methods of ceramics and, among them, the mechanical alloyed method (also known as Mechanical Activation) is a novel method used in the late years at laboratory level and industrial scale. This involves a combination of chemistry reactions and milling [Zhang et al] for the materials processing. The Mechanical Activation method is highly effective and economic compared with others methods that also promote the dopant diffusion in solid state reactions. The dopant atoms (Sr or Pb) in the perovskite structure, is used to improve the physical properties of the materials for diverse applications. Certainly, the chemistry bond nature is of crucial importance on these materials and therefore the valence electrons could be considered as responsible for the ferroelectric properties [Andrezj et al]. | |
