The potential of CaSnO3 for application as a capacitor component possessing a small
temperature coefficient of capacitance has been examined by ac small-signal
measurements at elevated temperatures (25300
C) in the frequency range 513 MHz. The
samples were synthesized by a novel technique called self-heat-sustained (SHS) reaction.
The ac data were acquired for the CaSnO3 samples sintered at various temperatures with
varying soak temperatures, T, and some times, t (1200
C T 1600
C; 2 h t 48 h). An
analysis of the electrical data in more than one complex-plane formalism indicated
