X-Ray Diffraction Analysis of Mechanically Milled Alumina and Zirconia Powders

Abstract

Ball milling is one of the top down approach used for reducing the particle size of bulk powder. Especially high energy ball milling is done to reduce the particle size to nanodomain. The Zirconia Toughened Alumina nanocomposite has diverged application in different engineering fields. The alumina and zirconia powders used for fabrication of Zirconia Toughened Alumina composite are subjected for ball milling. The effect of ball milling on the powders is reported on the work. The characterisation of the powder samples were done by X-ray diffraction. This was done to evaluate the effect of the starting material on the final product. Using the Scherer’s formula, Williamson-Hall analysis the change in crystallite size and strain were analysed.
