Low temperature synthesis of barium Zinc niobate using flux
Author(s): Ram Jeewan Yadav
Abstract: Barium Zinc Niobate i.e. Ba(Zn1/3Nb2/3)O3 (BZN) is a dielectric material and it has been employed in microwave communications. The single phase BZN powder was successfully prepared by using NaCl + KCl flux at the low temperature range 800-900oC. A systematic study indicating the effects of processing parameters, such as temperature, time, and amount of flux with respect to starting oxides, on the BZN formation mechanism and its resulting powder characteristics is reported. The phase compatibility, growth of particle size and difference in microstructures has been explained on the basis of powder XRD analyses and Scanning Electron Micrographs (SEM) images of the calcined samples.
