Fig. 3: TRIS-XRPD for Reaction I under ball mill neat grinding (NG) conditions with a loading of 70 mg.

a The reaction scheme for Reaction I under NG conditions. b Heat maps (linear intensity, arb. units) of TRIS-XRPD with empirical background subtracted data for Reaction I, alongside calculated 1D XRPD patterns for the reagents (KI + CsCl) and the final products (KCl + CsI). c Quantitative phase analysis for Reaction I obtained by Rietveld refinement, showing the consumption of KI (pink) and CsCl (green), with simultaneous formation of KCl (blue) and CsI (orange) with relative ESD bars. d Scherrer crystal size obtained for KI (pink), CsCl (green), KCl (blue) and CsI (orange) with relative ESD bars are shown for phases more abundant than 20 M%.
