Abstract
The dielectric constant of undoped, polycrystalline barium titanate in the paraelectric phase was obtained from the complex impedance plane representation in the 180–400°C temperature range, between 5 Hz and 13 MHz. A Curie-Weiss behavior is observed, with a Curie constant C o = 10.48 × 104 (K). These results are discussed and compared with results obtained with fixed frequency measurements.Keywords
