    Three different methods were used to obtain Bi Ti FeO ceramics, i.e. solid-state sintering, mechanical activation (MA) with subsequent thermal treatment, and electrical discharge assisted mechanical milling (EDAMM). The structure and magnetic properties of produced Bi Ti FeO samples were characterized using X-ray diffraction and Mössbauer spectroscopy. The purest Bi Ti FeO ceramics was obtained by standard solid-state sintering method. Mechanical milling methods are attractive because the Bi Ti FeO compound may be formed at lower temperature or without subsequent thermal treatment. In the case of EDAMM process also the time of processing is significantly shorter in comparison with solid-state sintering method. As revealed by Mössbauer spectroscopy, at room temperature the Bi Ti FeO ceramics produced by various methods is in paramagnetic state.
