A suitable powder feedstock was manufactured by blending a BaCO3 + Fe2O3 mixture, which was then agglomerated by spray-drying.
Table 1 represents compositions and amount of the modified mixture, which was applied for powder synthesis at each stage of chemical modification.
Water and ethanol were added to the obtained mixture, which was stirred well until the dissolution of the metal precursor was completed.
