This pale yellow solid, the simplest oxide of potassium, is a rarely encountered, highly reactive compound. Some materials of commerce, such as fertilizers and cements, are assayed assuming the percent composition that would be equivalent to K2O. ==Production== Potassium oxide is produced from the reaction of oxygen and potassium; this reaction affords potassium oxide, K2O. Treatment of the peroxide with potassium produces the oxide:〔Holleman, A. F.; Wiberg, E. "Inorganic Chemistry" Academic Press: San Diego, 2001. ISBN 0-12-352651-5.〕 : K2O2 + 2 K → 2 K2O Alternatively and more conveniently, K2O is synthesized by heating potassium nitrate with metallic potassium: :2 KNO3 + 10 K → 6 K2O + N2 Potassium hydroxide cannot be further dehydrated to the oxide but it can react with molten potassium to produce it, releasing hydrogen as a byproduct. 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「Potassium oxide」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.
