Investigation of dielectric and thermal properties of nano-filler (ZrO2) mixed enamel

In recent years, significant developments in nano-particles/fillers for electrical, thermal, and mechanical properties have been observed. In the present work, experimentally the dielectric and thermal properties of standard/nano-filled sample of enamel with Zirconia as filler have been critically examined. The dielectric loss (tan δ), dielectric constant (ε), insulation strength, partial discharge inception voltage and weight loss of the material have been studied under various operating conditions. It has been observed from the present investigation that 1wt% of Zirconia (ZrO₂) nano filler mixed enamel have improved dielectric and thermal properties.
