摘要：

Interactions between BaTiO3 and three binary glasses mere studied through the reaction of BaTiO3 powder with glass powder. For PbO-B2O3 and PbO-SiO2 glasses, the reaction led to stable compound formation, the substitution of Pb in the BaTiO33 structure, and noticeable grain growth of BaTiO3. The interaction phenomena for these two glass systems were very similar. The substitution of Pb into BaTiO3 is assisted by chemical reactions in which BaB2O4 or Ba2SiO4 is formed. The substitution into BaTiO3 also seems to be closely related to the grain growth of BaTiO3. On the other hand, only compound formation was observed during the processing of BaTiO3 with Bi2O3-B2O3 glass. Neither BaTiO3 grain growth nor Bi substitution took place with the Bi2O3-B2O3 glass system. Based on the observed reactions and the glass viscosity, several sintering aids for BaTiO3 ceramic products are suggested in this paper.
