Abstract

The effects of BaB2O4 glass on the synthesis of Ba2Ti9O20 were studied. The doping amounts of BaB2O4 varied from 0 to 10wt% and the compositions were sintered in the temperature range of 1200~1280◦C for 2h. The benefit of BaB2O4 addition to the densification of the ceramics is apparently due to the liquid phase which accelerates the migration of reactant species, which results in the decreasing of the sintering temperature. With the amount of BaB2O4 increased, the microstructure and properties of the ceramics were also changed: BaTi4O9 became the major phase instead of Ba2Ti9O20, bulk density decreased, and dielectric constant decreased accordingly, while dielectric loss kept small.
