Zusammenfassung:	To solve the problem of conventional active metal processing technology that uses molten salt, in which a metal oxide may not be fully contacted with an active metal, so the present invention provides active metal processing technology with which it is possible to improve the efficiency of a process of safely stabilizing the active metal using molten salt.SOLUTION: An active metal processing method pertaining to the present invention includes a step 17 in which an active metal 2 is reacted with a gas 4 for processing that includes oxygen atoms in molten salt 3 and the active metal 2 is transformed into a non-metal form. This way, it is possible to improve the efficiency of a process of safely stabilizing the active metal 2 using the molten salt 3.SELECTED DRAWING: Figure 2 【課題】従来の溶融塩を用いた活性金属処理技術では、金属酸化物が活性金属と充分に接触されないおそれがある。そこで、本発明では、溶融塩を用いて活性金属を安全に安定化させるための処理の効率を向上させることができる活性金属処理技術を提供する。【解決手段】本発明の活性金属処理方法は、活性金属２を溶融塩３中で酸素原子を含む処理用ガス４と反応させて活性金属２を非金属形態へ転換する工程１７を含む。このようにすれば、溶融塩３を用いて活性金属２を安全に安定化させるための処理の効率を向上させることができる。【選択図】図２
