Abstract Scope |
BaTiO3 doped with Ni2+ was synthesized from BaCO3, TiO2, and NiO as a powders using the solid state reaction method (Ba1-xNixTi1-x/4O3). The milling of the precursor was performed in an agate mortar with compositions x =0, 0.005, 0.01, 0.05, 0.1, 0.2 (%). The powder mixture it was sintered at 1200 °C for 5 hours evaluating two different heating ramps ( 2°C /min and 6°C/min ). Structural evolution of synthesized BaTiO3 doped with Ni2+ as a function of sintering speed was monitored by X-ray diffraction, Rietveld refinement and High resolution Scanning Electron Microscopy. The samples were compacted until to obtain pellets of about 10 mm of diameter and sintered at 1200 °C for 5 hours applying again the two different sintering ramps and its dielectric properties at 1KHz were determined. Important changes in the microstructure and capacitance value were found due to the sintering speed and doping of BaTiO3 with Ni2+. |
