Abstract
Zinc sulfide pellets sintered at 1200°C, 1000°C, 800°C and 600°C were partially oxidized in a single pellet reactor. Sulfur profiles of these samples were measured using Auger electron spectroscopy (AES) and electron probe microanalysis (EPMA). These profiles showed the coexistence of three zones: ash layer, reaction zone, and unreacted core. The zone thickness was found to be approximately the same for samples of comparable porosities. The effective diffusivities of sintered zinc sulfide pellets calculated by using the values of zone thickness measured in the present study compare well with the literature values reported from kinetic studies.
