Abstract:
Dielectric ceramics are the basic building block of every electronic device, especially for high-temperature applications, and enhancing its dielectric constant, dielectric loss polarization and a high electric breakdown strength plays a key role in producing advanced electronic components. So according to these facts, a new technique is used in this work to improve the dielectric properties of ceramics. This technique involves adding nano and micro (PbZrxTi1-xO3) Lead Zirconate Titanate PZT ceramic powders to the glaze layer of porcelain the dielectric strength for the glazed porcelain showed an increase of up to 30 wt % of the PZT additives in both nano and practical micro. Dielectric constant ԑ", Dielectric loss tangent tan δ and AC.conductivity showed an increase after glazing with nano-PZT higher than in micro-PZT.
