Abstract
The aim of this study is to synthesize barium titanate’s powders made by microwave assisted solvothermal method (MASM) and observe the effects of synthesis parameters on the structural properties. The studied parameters were: temperature, alkaline concentration of medium, acid washing and posterior sintering on half of the samples. The expected effects were that these establishments could produce dielectric active powders, free from impurities, of this material with a grain size in the nanoscale. The main results were satisfactory concerning to the purity of the samples according to the DRX of the material. However, the X-ray diffractions showed a cubic, or possible, pseudo cubic phase, becoming necessary a Rietveld refinement to make a more precise characterization of the material.
