Abstract
A method for purifying an organometallic compound in which an organometallic compound of gallium, aluminum or indium is contacted with at least one metal selected from metallic sodium, metallic potassium and a sodium-potassium alloy. This method is especially efficacious when the high-purity organometallic compound is used as a semiconductor because, by the disclosed method, the silicon components are removed as impurities, which silicon material tends to lower the electrical characteristics of the semiconductor.
