摘要： PURPOSE:To obtain high purity Ga crystals with high refining efficiency, at the time of crystallizing a Ga molten metal by pulling Ga crystals upward while they are rotated, by forming an acid soln. layer on the surface of the Ga molten metal. CONSTITUTION:At the time of crystallizing a crude Ga molten metal, e.g., recovered from scrap by a rotation upward pulling method, the surface of the Ga molten metal existing as a mother liquor is coated with an acid soln. layer. As the acid soln., the water soln. contg. strong acid such as hydrochloric acid, sulfuric acid, perchloric acid and formic acid is preferably used. Furthermore, the acid concn. of the acid soln. is generally regulated to the range of 0.05 to 5 N, preferably 0.1 to 1 N. Then, the acid soln. is brought into contact with the Ga molten metal as a mother liquor, by which impurity metals included in the Ga molten metal are melted away into the acid soln. Simultaneously, the impurity metals are oxidized by dissolved oxygen in the acid soln. and are precipitated as a solid matter. As the result, the sticking of Ga microcrystals including impurity metals into the surface of a crystal bar to be pulled up is prevented, by which high purity metallic Ga can be pulled up.

摘要： PURPOSE:To efficiently remove indium contained in gallium metal, by bringing gallium metal into contact with a refractory material consisting of the oxide of a specific metal under specific pressure and temp. conditions. CONSTITUTION:Gallium metal containing about several ppm - 5wt.% indium is brought into contact with a refractory material consisting of metal oxide at a temp. as high as its melting point or above. The proper temp. of the above treatment is >=800 deg.C, preferably about 1,000-1,400 deg.C. At this time, pressure is reduced to a residual-gas pressure of

摘要： PURPOSE:To recover liquid-metal gallium in high purity in high yield, by heating gallium-bearing material containing organic matters in a state of the aggregate of grains to coke the organic matters and then by applying vacuum thermal decomposition to the gallium-containing material. CONSTITUTION:A gallium-bearing material containing organic matters, such as dross as waste, is heated at -100mmHg degree of vacuum excluding the partial pressures of arsenic, phosphorus, gallium, etc., and also under the temp. condition of about 1,000-1,300 deg.C. By this method, arsenic and phosphorus are separated by sublimation, and high-purity metallic gallium can be recovered in a liquid state.
