Investigation of Structural, Morphological, Resistivity of Novel Electrical Insulator: Industrial Wastes

Panigrahi M.K

Abstract: In the present study, the effect of china clays on the sintering, strength and dielectric behavior of electrical ceramic fly ash/china clay (FA/CC) composite insulator is investigated. The different composition of samples containing different china clay (CC) contents of 10, 20, 30, 40, and 50 % are prepared using the uniaxial pressure technique applying 10 MPa pressure. At 1200 °C, for the composition having 40 wt% china clays, the maximum resistivity is calculated and is 39.5 × 107 Ωm. The composite is highly competence with china clays-based insulators. Further, the prepared composite is also analysed using different characterization technique such as x-ray diffraction, field emission scanning electron microscopy with energy dispersive analysis, fourier transformation infra-red spectroscopy, dielctric, and thermo gravimetric analysis. Frequency dielectric value of the composite is estimated at room temperature in the frequency range of 1-500 kHz at room temperature. According to the resistivity and dielectric properties, the composite has enormous potential for the electrical insulator application.
