Title: Oxidative dissolution of gallium arsenide and separation of gallium from arsenic

Patent ·
OSTI ID:6833764
;

The method of dissociating gallium arsenide into a gallium-containing component and an arsenic-containing component, is described which comprises contacting the gallium arsenide with an oxidizing agent and a liquid comprising hydroxamic acid to convert the gallium to a gallium-hydroxamic acid complex and to oxidize the arsenic to a positive valence state.
