Title: Morphological Investigations On Iron Potassium Sulfide Kfes2: Grinding Effect On Thermal Behavior
Author: Galembeck A.
Alves O.L.
Abstract: FeS2 (pyrite form), K2SO4, K3Fe(SO4)3 and α-Fe2O3 are the products of thermal decomposition of crystalline KFeS2, from room temperature up to 1000 °C, in air. Grinding of iron potassium sulfide prior to heating leads to a modified reaction pattern; the decomposition products are the same, but their formation temperatures are considerably lower than in the case of the unground crystals. Morphological features of the thermal reaction products are also considerably modified by KFeS2 grinding. © 1995.
