Il s'agit d'un solide blanc inodore insoluble dans l'eau. Ask your question. Answer Save. Potassium oxide is produced from the reaction of oxygen and potassium; this reaction affords potassium peroxide, K2O2. The chemical formula K2O (or simply 'K') is used in several industrial contexts: the N-P-K numbers for fertilizers, in cement formulas, and in glassmaking formulas. 1967]. Potassium hydroxide cannot be further dehydrated to the oxide but it can react with molten potassium to produce it, releasing hydrogen as a byproduct. Alternatively and more conveniently, K2O is synthesized by heating potassium nitrate with metallic potassium: Other possibility is to heat potassium peroxide at 500 °C which decomposes at that temperature giving pure potassium oxide and oxygen. Il en existe plusieurs polymorphes, le principal étant l'alumine α, rhomboédrique, qui existe dans le milieu naturel sous la forme du minéral appelé corindon, dont certaines variétés sont des pierres précieuses : le rubis, avec des traces de chrome, et le saphir, avec des traces de fer et de titane.
