The potential of CaSnO3 (calcium metastannate) for its application as a capacitor
component possessing small temperature coefficient of capacitance (TCC) in electrical
systems, is examined via the ac small-signal measurements. The ac electrical data were
acquired on these samples sintered at various combinations of temperature-time frames
(1200
C T 1350
C; 24 h t 60 h) in the frequency range from 5 Hz to 13 MHz. The
measurements were carried out over the temperature range 25300
C. The electrical
response was found to exhibit relaxation processes in more than one complex plane
