Abstract
In this work, Polarization–Electric field (P–E) hysteresis loop was evaluated and dielectric studies of the ceramic obtained from white rice husk ash (WRHA) and soda lime silica (SLS) glass was reported for electronic applications. Dielectric properties and hysteresis loop of the specimens were measured using a LCR meter and Sawyer–Tower circuit, respectively. The dielectric analysis clearly shows that the different amount of SLS glass content gives the different value of dielectric constant and loss to the ceramic. Sample with 2.5 wt% SLS glass content includes the lowest dielectric constant (11.13) among others, at 100 kHz, when sintered at 1,200 °C. The results show dielectric constant and loss of the specimens decrease with increasing applied frequency. P–E loop measurement indicates that the WRHA ceramic, generally, had capacitor capability and became more “resistor-like” than “capacitor-like”, with addition of SLS glass content.
