鉑族金屬二次資源等離子體冶金產(chǎn)物的物相分析

趙懷志

(昆明貴金屬研究所，昆明 650221)

摘要: 研究了題示冶金產(chǎn)物(鉑族金屬富集物)中的快冷物相。主體物相是以Fe或(Fe， Ni)為基體含鉑族金屬(PGM)的合金固溶體相。含Pt量高的富集物中有(Pt, Pd)固溶體相，含Si量高的富集物中有賦存PGM的Fe或Ni的硅化物相；微量Sn除分布在眾多的相中外，與PGM生成錫化物相。發(fā)現(xiàn)急冷合金化可生成ε-Fe亞穩(wěn)相、Fe-C亞穩(wěn)相。各物相中除主體成分外，都含有眾多的組元。快冷PGM富集物是多種非平衡物相的集合體。

ANALYSIS OF PHASES IN METALLURGICAL PRODUCTS OF PLASMA TREATING PGMs SECONDARY RESOURCES

Zhao Huaizhi

（Institute of Precious Metals, Kunming 650221, P. R. China）

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, ζ_βphase. 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: platinumgroup metal secondary resource plasma metallurgy phase
