本文讨论了双金属共存体系M_1-M_2-x-y,当两种金属的化合物相互作用生成多金属化合物时,优势区相图的绘制原理、方法及计算机程序。通过绘制Zn-Fe-SO系的优势区相图,分析了ZnO·Fe_2O_3的生成及稳定条件,并说明了其在硫化锌矿焙烧中的指导作用。
In this paper, the principle, method and computer program of the phase diagram of the dominant phase when the two metal compounds interact with each other to form the multimetallic compounds are discussed. By plotting the dominant phase diagram of Zn-Fe-SO system, the formation and stabilization conditions of ZnO · Fe 2 O 3 were analyzed, and their guiding role in the roasting of zinc sulfide ore was demonstrated.
