Preparation of ZnNb2O6 Powders by Molten Salt Method

Article Preview

Abstract:

ZnNb2O6 powders were prepared by solid phase method and molten salt method. KCl-NaCl-ZnCl2 was used as molten salt. The mass ratio of molten salt and raw material is 1:1. Pure ZnNb2O6 powders were synthesized by molten salt method at 650°C, which was reduced by 200°C relative to solid phase method. ZnNb2O6 powders preferably grow along special direction, and appear strip or rod like. ZnNb2O6 powders calcined at 650°C have narrow particle size distribution. Median size D50 =5.31μm. With the increase of the calcining temperature grain grows and particle size increases.
