Crystalline sulfur particles of predetermined, controlled, relative attrition resistance having diameters less than about 0.5 inch are formed by shock-crystallizing fused sulfur in an agitated quench medium by controlling the fused sulfur temperature at a predetermined level about 238 DEG F. and below 340 DEG F. correlated with the relative particle hardness desired, and controlling the sulfur-quench temperature gradient at a level of at least about 100 DEG F. Crystalline particles having higher relative attrition resistance are obtained at higher fused sulfur temperatures and higher quenching temperature gradients.
