Crystalline Microstructure of Zinc Oxide Powder Sintered into Varistor Body

Abstract:

Varistors obtained by sintering zinc oxide with additives were investigated. In this work the crystalline microstructure of ZnO varistor body is studied by X-ray diffraction method, before and after additional annealing. The crystalline microstructure is characterised by the prevalent crystallite shape, the volume-weighted crystallite size distribution, the second-order crystalline lattice strain distribution and the derivative quantities. The evolution of these characteristics, particularly of bimodal size distribution, elucidate some details of the formation of crystalline zinc oxide and provide additional arguments for explaining the change of the electric characteristics of varistors induced by annealing.
