Effect of BaCu(B2O5) (BCB) on the sintering behavior and dielectric properties of (SrLa)(TiAl)O3 (SLTA) ceramics were investigated in this paper. The sintering temperature of the SLTA ceramics, which could be conventionally sintered at approximately 1600oC, was efficiently lowered as much as approximately 150oC by the addition of BCB. The SLTA ceramics doped with a small amount of BCB could be well sintered at 1450oC without degrading their dielectric properties. In particular, the 0.05 wt% doped SLTA ceramics, sintered at 1450oC for 2h, exhibited optimum dielectric properties of dielectric constant (41) and quality factor (41,000 GHz). Therefore, BCB could be a suitable sintering aid to improve densification of the SLTA ceramics at very low temperature. |
