| Abstract Scope |
The BaTiO3 is a polycrystalline ceramic material at environment temperature presents tetragonal structure, but when this material exceeds the transition temperature, it suffers a transformation to the cubic phase called Perovskita. Through a solid-state reaction synthesis process, the effect of doping on samples x = 0.009, 0.10, 0.20 % by weight Eu3+ was investigated, the grinding with zirconia ball was made for 3 hours and acetone as a control agent. Subsequently, 900 °c were heated for 5 hours, followed by a temperature sintering of 1300 °c. The results obtained were analyzed by X-ray diffraction where the tetragonal BaTiO3 consolidation is shown, by scanning electron microscopy show a homogeneous distribution of the sintering particles and the formation of necks characteristic of the sintering process and the elementary distribution maps shows the concentration of the elements in the sintering ceramics at 1300 °c. |
