Study of subcell parameters, grain size and dielectric properties of Potassium Sodium Niobate mixed system

Abstract

Pellets of K_1-xNa_xNbO₃ mixed system of different concentration have been prepared by solid solution reaction method. The subcell parameters & grain size have been calculated using X-ray diffraction data for mixed K_1-xNa_xNbO₃ system where x is varied from 0, 20, 40, 50, 80, 100%. The variation of unitcell parameters and grain size with composition, at room temperature have been reported. Dielectric constant and loss tangent at room temperature and at different frequencies have also been reported.
