Pyroelectric properties of lead-barium titanate and lead-strontium titanate

Abstract

Pyroelectric properties of poled solid solutions of lead-barium titanate and leadstrontium titanate have been investigated in the temperature range covering their transition points. The values of pyroelectric current and coefficients of (Pbx - Ba1 -x )TiO3 and (Pbx - Sr1 -x )TiO3(x = 0·8 - 0·5) show a sharp peak at the Curie temperature. It is observed that these values change with Ba or Sr concentration in the respective solid solutions. © 1987 Indian Academy of Sciences.
