A new low loss spinel microwave dielectric ceramic with composition of ZnLi 2/3 Ti 4/3 O 4 was synthesized by the conventional solid-state ceramic route. The ceramic can be well densified after sintering above 1075°C for 2h in air. X-ray diffraction data show that ZnLi 2/3 Ti 4/3 O 4 ceramic has a cubic structure [Fd-3m (227)] similar to MgFe 2 O 4 with lattice parameters of a=8.40172Å, V=593.07Å 3 , Z=8 and ρ=4.43g/cm 3 . The best microwave dielectric properties can be obtained in ceramic with relative permittivity of 20.6, Q×f value of 106,700GHz and τ f value of −48ppm/°C. The addition of BaCu(B 2 O 5 ) (BCB) can effectively lower the sintering temperature from 1075°C to 900°C and does not induce much degradation of the microwave dielectric properties. Compatibility with Ag electrode indicates that the BCB added ZnLi 2/3 Ti 4/3 O 4 ceramics are good candidates for LTCC applications.
