Effect of Sintering on Time Domain Response of CaTiO3 Nano Ceramics

Abstract

High-energy ball milling(HEBM) used for synthesize nano crystalline Calcium Titanate, CaTiO3 (CT) ceramic. X-ray diffraction(XRD), impedance and time domain analysis applied for characterization. Effect of grain conduction observed from complex impedance spectrum in the Nyquist plot by the appearance of one semi-circular arc. Various time response parameters have been calculated. Green pellets in disk shaped sintered at 1000°C, 1100°C and 1200°C to study the effect of sintering on time response. Time domain response obtained by MATLAB programming of equivalent circuit parameters got from cole-cole plot of respective samples using partial fraction and inverse Laplace transform method. Potential of nano CaTiO3 as faster sensitive material for electrical and electronic device applications proven by the study.
