  A rich variety of dielectric, optical, acoustic/piezoelectric, ferromagnetic properties of ferroelectric and multiferroic composite materials open a new perspective for the development of modern accelerators with new principle of electron acceleration and control system. These properties may be controlled by external electric fields. In particular, the production of electric field controlling ultrafast facilities for 0.7-20 GHz RF phase shifting and amplitude modulation where a very short response time of <10 nsec is required . A Self-propagating High-temperature Synthesis (SHS) technology for obtaining ceramic materials, based on (1-x)BiFeO3-xBaTiO3 compositions with various dopant (MgO, MnO, etc.), 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), as well as electro physical properties 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.
