High temperature synthesis of barium Zinc Niobate with flux

Author(s): Ram Jeewan Yadav
Abstract: The complex perovskite oxide Ba(Zn1/3Nb2/3)O3 (BZN) have been widely studied due to its attractive dielectric properties which place this material as a good candidate for manufacturing type I capacitors or hyperfrequency resonators. The processing conditions e.g. soaking temperature and time, amount of flux, and composition of the flux influence the properties and dielectric parameters of the materials. Formation of secondary phase occurs at high calcinations range of temperatures (beyond 1300oC). BZN is extensively employed in microwave communications. The single phase BZN can be successfully prepared by using NaCl + KCl flux at a wide range of temperatures. The phase compatibility, growth of particle size and difference in microstructures have been explained on the basis of powder XRD analyses and Scanning Electron Micrographs (SEM) images of the calcined samples.
