DRAWING PREDOMINANCE DIAGRAM OF M_1-M_2-x-y SYSTEM AND ITS APPLICATION
M1—M2—X—Y系优势区相图的绘制及其应用

Discussions were made of the principle, method and computerizedprogram for drawing the predominance diagrams of the bi-metal co-existed systemM_1-M_2-x-y in which the multimetallic compounds may be produced by interactionbetween compounds of both metals. The formation of zinc ferrite and its stableregion have been analyzed through drawing Zn-Fe-S-O system predomincance dia-gram. The availability of the diagram is given the direction to roast the zinc sul-fide ore as well.
