Ball milling induced reduction of SrSO4 by Al - ScienceDirect

2011-3-9  The reduction of celestite concentrate to SrS using Al has been shown to be induced by mechanical activation. A thermodynamic appraisal showed that the reaction between SrSO 4 and Al is highly exothermic and should be self-sustaining. XRD analyses showed that reaction started only after milling for an induction time of 30–35 min, after induction only product peaks were present.
