  The powder of barium titanate (BaTiO3) synthesized by solid state was
characterised by spherical grains of the average size about 500 nm. The double
mechanical activation and calcination of raw materials was necessary to receive
the monophase material. In order to improve the mouldability, the obtained
barium titanate powder was granulated in spray drier. Pellets and beams from
BaTiO3 granulate were manufactured by both uniaxial and isostatic pressing. The
properties of barium titanate material at each stage of its fabrication
(powder, granulate, sintered material) influencing on its application for the
stacked-disk multilayer actuator were determined. Particularly, the four
parameters of BaTiO3 sinter affecting on the usability properties of actuators,
not found before in the literature, were estimated.
