BaTiO3 was prepared by mechanochemical synthesis. A powder mixture of BaO and TiO2 was treated in a planetary ball mill in an air atmosphere for up to 12 h, using zirconium oxide vial and zirconium oxide balls as the milling medium. After 60 minutes BaTiO3 phase was formed. BaTiO3 ceramic was sintered after 120 min on 1300 ºC without pre-calcinations step. The heating rate was 10 ºC min-1. The formation of phase and crystal structure of BaTiO3 was approved by XRD analysis and Raman spectroscopy. The morphology and microstructure of obtained ceramic powders were examined by SEM method. Sample BaTiO3 obtained from mechanically activated oxides mixture sintered at 1300 ºC for 2 h exhibits a hysteresis loop, confirming that the synthesized material possesses ferroelectric properties..

Active accounts were imported to the new platform and assigned a random password by default. In order to access your account you need to access the login page and go through the Lost Password dialog (involves the system sending you an email with instructions) in order to reset your password. This step is necessary as passwords are kept in hashed form and the new platform uses modern hashing algorithms incompatible with the previous ones.
