An emulsion technique and spray drying were used to prepare BaTiO 3 powders coated with additives. Different additive compositions (TiO 2 ; TiO 2 /SiO 2 ; CaO/TiO 2 /SiO 2 ; 2BaO/TiO 2 /2SiO 2 ) were used in the form of their aqueous precursor solutions. The as-received powders were compared with powders of the same composition manufactured by conventional wet-milling. The coating of the BaTiO 3 powder positively influences the sintering behavior. Isothermal dilatometric measurements show that the activation energy ΔE of the shrinkage of the coated powders is lower than that of the powders prepared by milling. This is caused by the homogeneous distribution of the additive. The activation energy for the different additives changes in the following sequence: ΔE(2BaO/TiO 2 /2SiO 2 ) < ΔE(TiO 2 ) < ΔE(CaO/TiO 2 /SiO 2 ) < ΔE(TiO 2 /SiO 2 ). This sequence correlates with the amount of Ba ions necessary to diffuse out of the BaTiO 3 matrix to form the secondary phases Ba 2 TiSi 2 O 8 or Ba 6 Ti 17 O 40 , respectively.
