The XRD measurements were performed on powder to identify the minerals in the ceramic body, using a diffractometer (D8-Advance, set in Bragg–Brentano reflection mode, Bruker AXS, Karlsruhe, Germany) and an X-ray tube with Cu Kα radiations operating at 40 kV and 40 mA. The measurements were recorded from 3° to 60°, with a scan step size of 0.01° and an acquisition time step of 1 s. Qualitative analysis of the obtained diffractograms was realized with EVA software using the PDF-2004 database from ICDD. In addition, a Rietveld refinement was applied by using TOPAS software, in order to quantify the mineral phases.
