A Bruker D8 DISCOVER with DAVINCI.DESIGN diffractometer with a
CoKα tube was used to perform XRD analysis and identify the phases
formed. 2D frames were collected with DIFFRAC. Measurement Centre
Version 3.0 software was integrated to 1D using DIFFRAC.EVA Version
4.0 (all from Bruker-AXS). A pattern search/match was then executed
using the integrated ICDD PDF-2 2011 powder database.
