Quantitative Analysis of Tetragonal Phase in Mg-PSZ by X-ray Diffraction

Abstract

A quantitative analysis of the tetragonal phase in Mg-PSZ by a standard X-ray powder diffraction method was carried out using the diffraction intensities with the Miller indices (311). The volume fraction of the tetragonal phase is shown to be given by
Vt=2.92/(1+0.991 X), where X={I_t(311)+I_c(311)}/I_t(113) which involves the diffraction intensities It and Ic of the corresponding tetragonal and cubic phases. The standard error of this method was estimated to be 4.5%. The present result is applicable to evaluate the tetragonal phase and the cubic phase in Mg-PSZ which contains the monoclinic phase less than 37%.
