文摘
- •
BT and SiO2 added ceramics were obtained by microwave sintering at low temperature.
- •
Pure BT ceramic showed very high dielectric constant (11022) at Curie point.
- •
Increasing SiO2 addition, Ba2TiSi2O8 was detected and columnar grains appeared.
- •
Improvement of densification and second phase were effective to improve the BDS.
