A Low Sintering Temperature Low Loss Microwave Dielectric Material ZnZrNb_2O_8

摘要

A low sintering temperature microwave dielectric material ZnZrNb_2O_3 was reported. It exhibits a monoclinic structure, belongs to the space group P2/c (C_(2h)~4), and Z = 1. The dielectric constant increased with increasing relative density. The Qf value increased with increasing packing fraction. The τ_f increased with increasing dielectric constant. The typical values of ZnZrNb_2O_8 were ε = 30, Qf= 61 000 GHz, τ_f=-52 × 10~(-6) ℃~(-1), sintered at 950℃.
