Abstract

In this study full dense polycrystalline samples of Pb(Mg1/4Ni1/4W1/2)O3 have been sintered by solid-state reaction. X-ray data showed the formation of a single-phase new compound with unit cell parameters a = 9.8045 (25) Å, b = 13.1280(25) Å and c = 14.4207 (25) Å. Scanning electron microscopy (SEM) was used to evaluate the microstructures of sintered specimens. Dielectric constant and loss as function of frequency were investigated.
