The exaggerated grain growth (sometimes referred to as secondary recrystallization) during sintering of BaTiO₃ was studied with two different liquidforming additive oxides, TiO₂ and SiO₂. The liquid phase was distributed inhomogeneously by placing a small amount of TiO₂ and SiO₂, respectively, on top of the BaTiO₃ powder compact. The exaggerated grain growth was observed to occur more rapidly in the SiO₂-containing specimen than in the TiO₂-containing specimen. Once the initial fine-grained structure was completely replaced by the exaggeratedly grown grains, the TiO₂-containing specimen exhibited practically no more micro structural evolution. For the SiO₂-containing specimen, on the other hand, a few grains continued to grow without limit. The observed unusual growth has been explained in terms of twin-assisted growth mechanism.
