Very pure barium titanate is obtained by coprecipitation of barium and titanium compounds (e.g. as oxalates or citrates) followed by calcination. In the manufacture of electroceramics, this is followed by the usual ceramic processes grinding, molding and a sintering at 1300°C. 

Cadmium Yellow. Cadmium sulphide, coprecipitated with barium sulphate. Cadmium Zirconate. CdZr03 occasionally used as an addition to barium titanate bodies, the effect being to reduce the dielectric constant and Curie temperature.
