MICROWAVE DIELECTRIC-PROPERTIES OF CERTAIN SIMPLE ALKALINE-EARTH PEROVSKITE COMPOUNDS AS A FUNCTION OF TOLERANCE FACTOR

Microwave dielectric properties of some simple alkaline earth perovski te compounds were studied with respect to the variation in the toleran ce factor. It was found in the present study that the variation in die lectric constant (epsilon), Q . f(o) product and the temperature coeff icient of polarizability with tolerance factor is quite opposite to wh at is observed in some complex perovskite materials. It was also obser ved that the temperature coefficient of dielectric constant follows th e same trend as in some complex perovskite materials with respect to t he tolerance factor.
