摘 要: 研究了题示冶金产物(铂族金属富集物)中的快冷物相。 主体物相是以Fe或(Fe， Ni)为基体含铂族金属(PGM)的合金固溶体相。 含Pt量高的 富集物中有(Pt, Pd)固溶体相， 含Si量高的富集物中有赋存PGM的Fe或Ni的硅化物相； 微量Sn除分布在众多的相中外， 与PGM生成锡化物相。 发现急冷合金化可生成ε-Fe亚稳相、Fe-C亚稳相。 各物相中除主体成分外， 都含有众多的组元。 快冷PGM富集物是多种非平衡物相的集合体。

Abstract:The phases in the platinum-group metals (PGMs) concentrating matter from plasma metallurgy have been analysed. The main composite phases are (γFe, Ni), (Fe, Pt), (Pt, Pd) solid solutions, Fe-C phase, ε-Fe metastable phase. The subordinate phases are compounds:Ni3Si2, Ni3Fe, PdSn, ζβ phase. With composition change in concentrating matter there occur some differences in phase species and number. The concentrating matter is an aggregate of nonequilibrium phases, which contain platinum-group metals.
Key words: platinumgroup metal secondary resource plasma metallurgy phase
