It is named after German chemist Adolf Sieverts (1874–1947). The law states that the solubility of a diatomic gas in metal is proportional to the square root of the partial pressure of the gas in thermodynamic equilibrium.〔C. K. Gupta, "Chemical metallurgy: principles and practice", Wiley-VCH, 2003, p.273.〕 Hydrogen, oxygen and nitrogen are examples of dissolved diatomic gases of frequent interest in metallurgy. == Justification == Sieverts' law can be readily rationalized by considering the reaction of dissolution of the gas in the metal, which involves dissociation of the molecule of the gas. For example, for nitrogen: :N2(gas) 2 N(dissolved) For the above reaction, the equilibrium constant, K, is: :$K^2\; =$ Where: * C is the concentration * p is the partial pressure Therefore, :$C\_N\; =$ 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Sieverts' law」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
