<P>PROBLEM TO BE SOLVED: To provide a method for inspecting a refined metal ingot, whereby impurity concentration in a refined metal ingot obtained from metal melt through solidifying segregation can be readily screened, and a production method of a high-purity metal containing the same, and application thereof. <P>SOLUTION: The method for inspecting the refined metal ingot comprises: bringing a refined ingot support into contact with the metal melt containing impurities; and subsequently inspecting whether the refined metal ingot is favorable or unfavorable, which is determined by the impurity concentration contained in the refined metal ingot of the metal melt deposited onto the surface of the refined ingot support through solidifying segregation, based on the surface condition of the outer periphery of the refined metal ingot. <P>COPYRIGHT: (C)2013,JPO&INPIT |
