Characterisation of a Complex CaZr0.9Ce0.1Ti2O7 Glass–Ceramic Produced by Hot Isostatic Pressing
Abstract
<p>The behaviour of Ce-containing zirconolites in hot isostatically pressed (HIPed) materials is complex, characterised by redox interactions between the metallic HIP canister that result in reduction of Ce<sup>4+</sup> to Ce<sup>3+</sup>. In this work, a glass–ceramic of composition 70 wt.% CaZr<sub>0.9</sub>Ce<sub>0.1</sub>Ti<sub>2</sub>O<sub>7</sub> ceramic in 30 wt.% Na<sub>2</sub>Al<sub>2</sub>Si<sub>6</sub>O<sub>16</sub> glass was produced by HIP (approx. 170 cm<sup>3</sup> canister) to examine the extent of the material–canister interaction. A complex material with six distinct regions was produced, with the extent of Ce reduction varying depending on the distance from the canister. Notably, the innermost bulk regions (those approximately 7 mm from the canister) contained only Ce<sup>4+</sup>, demonstrating that a production-scale HIPed glass–ceramic would indeed have a bulk region unaffected by the reducing environment induced by a ferrous HIP canister despite the flow of glass at the HIP temperature. Each of the six regions was characterised by XRD (including Rietveld method refinements), SEM/EDX and linear combination fitting of Ce L<sub>3</sub>-edge XANES spectra. Regions in the lower part of the canister were found to contain a significantly higher fraction of Ce<sup>4+</sup> compared to the upper regions. Though zirconolite-2M was the major crystalline phase observed in all regions, the relative abundances of minor phases (including sphene, baddeleyite, rutile and perovskite) were higher in the outermost regions, which comprised a significantly reduced Ce inventory.</p>
