Structure, electrical and magnetic property investigations on Fe-doped hexagonal BaTiO3

A powder mixture of BaCO3 and TiO2 was mechanochemically treated in a planetary ball mill in an air atmosphere for up to 80 h, using tungsten carbide balls as the milling medium. Mechanochemical reaction leads to the gradual formation of BaTiO3 phase. Phase evolution during synthesis and changes in powder size and morphology were monitored by XRD, VSM, BDS and FE-SEM analysis and it was shown that the formation of BaTiO3 phase. Extended time of milling directed to formation of higher amount of BaTiO3 perovskite phase. Barium titanate with good nanopowered was formed after 6 h sintering without pre-calcination step was performed at 1000 °C for 6 h and 1200 °C for 6 h within heating rate 10 °C/min.
