| Abstract: | The influences of BaCu(B2O5) (BCB) addition on sintering, microstructure and microwave dielectric properties of Li2MgTi3O8 ceramics were investigated using X-ray diffractometry, scanning electron microscopy and microwave dielectric measurements.
The experimental results show that a small amount of BaCu(B2O5) addition can effectively reduce the sintering temperature to 900 °C, and induce only a limited degradation of the microwave
dielectric properties. Typically, the best microwave dielectric properties of ɛ
r=24.5, Q×f =24 622 GHz, τ
f=4.2×10−6 °C−1 are obtained for 1.0% BCB-doped Li2MgTi3O8 ceramics sintered at 900 °C for 3 h. The BCB-doped Li2MgTi3O8 ceramics can be compatible with Ag electrode, which may be a strong candidate for low temperature co-fired ceramics applications. |
