  • Synthesis and characterization of BaTio3 powder prepared

    The solid state route needs high calcinations temperature to get perovskite phase and often results in the formation of multiphase and inhomogeneous powders. High energy ball milling is also reported to produce 10nm particle size but the approach suffers from small batch size high processing time and energy consumption.

    Abstract. In this research the mechanical activation method is proposed as an alternative process of preparation of the (BiFeO 3) 1-x-(BaTiO 3) x solid solutions with various concentrations of barium titanate (x = 0.1÷0.9). However mechanical milling itself does not allow obtaining the desired products and additional thermal treatment is needed to complete the solid-state reaction.
