Dielectric and pyroelectric properties of sintered discs of sodium meta vanadate

Abstract

The dielectric and pyroelectric properties of poled and unpoled sintered discs of sodium meta vanadate were investigated in the temperature range from room temperature to 450°C. Dielectric constant and loss tangent anomalies were found around 375–390°C, while in pyroelectric coefficient, two anomalies were noticed at 250±25°C and 360±50°C respectively
