Description

The goal of this project was to separate a binary, eutectic composition alloy into its pure elemental components by modifying the SLICE (Shearing Liquids Into Complex ParticlEs) technique. The Bismuth-Tin eutectic alloy was chosen as a proof of concept system before expanding to alloys containing toxic or critical elements. It has been shown using EDS and XRD that shearing tin-bismuth eutectic alloy above its melting temperature in an acetic acid/diethylene glycol solution will separate the bismuth from the tin to 99 wt% purity bismuth.
