Abstract

PURPOSE:To easily recover high-purity gallium in a short time, by subjecting gallium-containing scrap to chlorination and distillation separation to prepare crude gallium chloride, reducing the above aqueous solution with metal, and then applying distillation to the above under reduced pressure. CONSTITUTION:Gallium-containing scrap such as gallium-arsenic and gallium- phosphorus, is crushed and charged into a dissolution vessel, where gallium and other element are chlorinated by means of chlorine gas. After or simultaneously with the chlorination, distillation separation is applied, by which AsCl3, PCl3, etc., are removed and crude gallium chloride composed principally of GaCl3 and GaCl2 is obtained. Further, rechlorination treatment is applied to convert GaCl3 into GaCl2 with lower boiling point, which is distilled and rectified into refined gallium chloride. Subsequently, this aqueous solution of refined gallium chloride is reduced by metal (zinc, etc.) and then subjected to vacuum refining at about 200-1,000 deg.C under a pressure of about 0.01-10Torr to undergo impurity removal. By this method, high-purity metallic gallium can be recovered and used as semiconductor material.
