摘要

The BaTiO3BaTiO3 is a polycrystalline ceramicCeramic material which at environment temperatureTemperature presents tetragonal structure, but when this material exceeds the transition temperatureTemperature, it suffers a transformation to the cubicCubic phase called PerovskitePerovskites. Through a solid-state reaction synthesisSynthesis processProcess, the effect of dopingDoping on samples x = 0.009, 0.10, 0.20% by weight Eu3+Eu3+ was investigated, and the grinding with zirconia ball was made for 3 h with acetone as a control agent. Subsequently, at 900 °C heated for 5 h, followed by a temperatureTemperature sinteringSintering of 1300 °C. The results obtained were analyzed by X-ray diffraction where the tetragonal BaTiO3BaTiO3 consolidation is shown, which by Scanning Electron MicroscopyScanning Electron Microscopy (SEM) show a homogeneous distribution of the sinteringSintering particles and the formation of neck characteristic of the sinteringSintering processProcess and the elementary distribution maps shows the concentration of the elements in the sinteringSintering ceramicsCeramic at 1300 °C.
