摘要

Phase relation in the zinc-iron-sulfur ternary system, which is of fundamental importance for discussing a new zinc distillation process with environmental comsciousness previously proposed by the authors, has been investigated at temperatures of 1100 and 1200 K by equilibrating synthetic samples in evacuated sealted quartz tubes. Using the activities of iron and zinc in the iron-zinc binary system, the activities of the components in the zinc-iron-sulfur ternary system were calculated by applying the Gibbs-Duhem equation to the phase relation of metal-sulfide equilibrium in the zinc-iron-sulfur ternary system. The raction path of the new zinc distillation process, in which zinc sulfide is directly reduced to zinc vapor with metallic iron and the sulfur in zinc sulfide is fixed as pyrrhotite, will be discussed in terms of the activities of the components in the zinc-iron-fulfur ternary system.
