Dielectric properties of 2-2 PMN-PT/cement composites
Dielectric properties of 2-2 connectivity lead magnesium niobate-lead titanate (PMN-PT)/Cement composites were investigated at 0.1-20kHz. PMN-PT of 60-80% by volume was used. The composites were fabricated using a dice and fill technique and cured in 98%RH curing chamber for 7days before measurement...

| Summary: | Dielectric properties of 2-2 connectivity lead magnesium niobate-lead titanate (PMN-PT)/Cement composites were investigated at 0.1-20kHz. PMN-PT of 60-80% by volume was used. The composites were fabricated using a dice and fill technique and cured in 98%RH curing chamber for 7days before measurements. Dielectric constant (εr) at 1kHz increased with PMN-PT volume, having values of 1504, 1645 and 2390 respectively. Dielectric loss (tan) values are 0.382, 0.185 and 0.188 at 1kHz. In addition, the dielectric constant was found to decrease with an increase in the frequency tested having value of 1692, 1504 and 1322 for 0.1, 1 and 20kHz respectively. The dielectric loss was found to be less with increasing frequency at 0.702, 0.382 and 0.179 for 0.1, 1 and 20kHz respectively. Copyright © Taylor & Francis Group, LLC. |
