Ba2Ti9O20 Ceramic from BaSO4 AND TiO2 Powder Synthesis Mixture
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.
