Research on Hydrometallurgical Purification of Microimpurity in SiGe Alloy Tailings

Abstract:

Microimpurities are introduced by CZ of SiGe alloy, by studying the possibility of using hydrometallurgical route to refine SiGe alloy, different influencing factors were investigated, and the samples were characterized by SEM, ICP etc. When SiGe alloy particles are leached at appropriate conditions: the size 100-400μm, the mol fraction of HCl 2mol/l, reaction time 8h, reaction temperature 40°C, Impurities mass fractions of Fe, Al, Ca could be reduced to 4.14ppmw, 18.30ppmw, 78.99ppmw, the removal ratio are 99.23%, 84.36%, 34.18%, and the impurity content is reduced to about 100ppmw.
