Abstract
A Self-propagating High-temperature Synthesis (SHS) technology for fabrication of Mn doped 0,67BiFeO3–0,33BaTiO3 (BF–BT) multiferroelectric ceramic targets has been developed. The general parameters of the SHS process (temperature and propagation velocity of the combustion front) are measured. The dependences of microstructure (grain size, density, and porosity of the sintered samples) on compaction and sintering thermodynamic variables, such as the pressing pressure and duration, sintering temperature, sintering duration and atmosphere, heating and cooling rates are experimentally investigated.
