Structural analysis of orthorhombic ZrO2 by high resolution neutron powder diffraction.

Abstract

A time-of-flight neutron diffraction experiment was undertaken on a powder sample of orthorhombic Zr02 synthesized at 600C and 6 GPa for 30 min. The Rietveld analysis for the diffraction data shows that the space group of this phase is Pbca. The refined lattice parameters are a0=1.00861, b0=0.52615, and c0=0.50910 nm.
