Abstract
In this study, two types of sulfur equilibration experiments were conducted using either a conventional thermal gravimetric analysis (tga) technique or a horizontal tube furnace apparatus. Samples were equilibrated with flowing so2-o2 gas mixtures of 58% or 10% so2. The experiments were (1) the investigation of the extent of solid solution of sulfur in zno, nio, cuo, and fe2o3 over a wide range of temperature, and (2) studies of compound or solid solution formation between binary sulfate mixtures of fe-zn, cu-zn, ni-zn, fe- cr, and cd-zn by tga. There was no appreciable solid solution and/or compound formation indicated from any of the mixtures of two different sulfates investigated, except for znso4-cdso4, which exhibited compound formation.
