Crystal Structure of Zinc Calcium Oxysulfide

摘要

Zinc calcium oxysulfide is an intermediate product in recovery of zinc from its sulfide by carbothermal reduction in the presence of lime.A new quaternary oxysulfide was first reported in [1].Later on,Igiehon and coworkers[2,3]tried to investigate the products of carbothermal reduction of iron and zinc sulfides and to determine the crystal structures of ZnCaOS and FeCaOS.
