(a) XRD and Rietveld refinements of all Cu-containing (2, 4 and 8 wt% Cu) SPR-212 mixtures after mixing at 130°C, with (b) fitted nanoparticle sizes from refinements of all copper loadings processed to 130, 700 and 1000°C. The results show an increase in nanoparticle size with increased copper loading, and an increase in nanoparticle size with increasing processing temperature. |
