dielectric dissipation loss factor

The experimental results show that the piezoelectric charge constant(d33),relative dielectric constant(εr) and dielectric dissipation loss factor(tanδ) decrease dramatically with increasing amount of doped Co2O3 in a rang from 0 to 0.

4%,介電損耗因子tanδ大幅降低,同時壓電常數d33和介電常數εr降低。

At low temperature,dielectric constant ε(ε' ,ε'' ),dielectric loss tangent tgδis small at ω<104Hz or ω> Hz.
