“…In this work, new catalysts have been synthesized by means of a sol-gel method by using precursors and reagents which have already been used in other synthesis studies [27,28]. However, in this work, the effect of separating the aggregates after aging and prior to calcination has been evaluated.…”

“…The microstructure control is, therefore, the key for enhancing the BaTiO 3 ceramics electrical performances, and it is only possible by using non-conventional preparation methods such as sol--gel, oxalate, hydrothermal synthesis, citrates and polymeric precursors method, mainly based on the Pechini--type process [4]. The advantage of the Pechini method (polymeric precursor method) is based on the fact of its simplicity and possibility to hold the initial stoichiometry [5].…”

Barium titanate, BaTiO3 ceramic powders were prepared by mechanochemical synthesis and by the Pechini method. A powder mixture of BaO and TiO2 was treated in a planetary ball mill in an air atmosphere for up to 1 h, using zirconium oxide vial and zirconium oxide balls as the milling medium. After 60 min BaTiO3 phase was formed. In both ways BaTiO3 ceramics were sintered after 2 h on 1300 • C without pre-calcinations step. The heating rate was 10 • C min −1 . The formation of phase and crystal structure of BaTiO3 was approved by X-ray diffraction analysis and the Raman spectroscopy. The morphology and microstructure of obtained powders were examined by scanning electron microscopy method. Sharp phase transition from ferroelectric to paraelectric state was observed. The hysteresis loop is very well performed with regular sharp characteristic of ferroelectric materials.
