Investigation on Dielectric Constant of Zinc Oxide

The studies of the behavior of zinc oxide and its dielectric constant at different temperature ranging from 700 C (975K) up to 1000 C (1275K) have been done, as well as the fabrication of pellet. The pellets were sintered at 700 C, 800 C, 900 C and 1000 C, in a Nabertherm Controller Furnace and the heating rate is 6 C/min. The capacitance and dissipation factor (tan ) were taken and calculated the relative permittivity, r and dielectric loss, i which are indicated the behavior and dielectric constant of zinc oxide that depend on different temperatures of sintered pellet and frequency of the applied LCR meter .
