Interactions between BaTiO 3 , and three binary glasses were studied through the reaction of BaTiO 3 , powder with glass powder. For PbO–B 2 O 3 and PbO–SiO 2 glasses, the reaction led to stable compound formation, the substitution of Pb in the BaTiO 3 structure, and noticeable grain growth of BaTiO 3 . The interaction phenomena for these two glass systems were very similar. The substitution of Pb into BaTiO 3 is assisted by chemical reactions in which BaB 2 O 4 or Ba 2 SiO 4 is formed. The substitution into BaTiO3 also seems to be closely related to the grain growth of BaTiO 3 . On the other hand, only compound formation was observed during the processing of BaTiO 3 with Bi 2 O 3 –B 2 O 3 glass. Neither BaTiO 3 grain growth nor Bi substitution took place with the Bi 2 O 3 –B 2 O 3 glass system. Based on the observed reactions and the glass viscosity, several sintering aids for BaTiO 3 ceramic products are suggested in this paper.
