| Description |
It has been observed that low-temperature ( 950 degrees C) fast-fired Pb(Zr0.52Ti0.48)O-3 (LTFF-PZT) shows strong low-frequency dispersion (LFD). Considering the presence of inhomogeneity (clusters) in LTFF-PZT, such LFD can be explained by the universal dielectric response (UDR) formalism. In the presence of moisture, LFD is exaggerated in conformity with the principle of UDR, where the long-range, cooperative interactions are enhanced due to screening of the surface field of the ferroelectric by polar water molecules. Preliminary study indicates that LTFF-PZT can be exploited to make novel pore-free moisture sensors
