Abstract
In this work the BaSO4 powder was synthesized from BaCO3 powder that
was attacked with HCl. Then BaCl2 was precipitated in (NH4)2 SO4, containing TiO2
powder. The influences of processing and TiO2 particles presence were investigated by
X-rays diffraction and SEM. It was found that the washing of BaSO4 - TiO2 precipitated
by ethanol greatly benefited the formation of smaller size particles.
