高价镍的氧化物用于废气废水处理,效果良好。利用它的强氧化性制成镉、镍碱性电池,可作为人造卫星、宇宙飞船的高能电源。然而,目前对于在氧化物中镍的氧化态及高价氧化镍的存在形式问题,认识还不一致。多数认为:三价镍的氧化物仅能以含水形式存在,而无水三氧化二镍的存在尚未得到证明。本文介绍用电解氯化镍(Ⅱ)制备三价镍的氧化物。通过热分析,配合化学分析与仪器分析,确证经高 High-priced nickel oxide for exhaust gas wastewater treatment, the effect is good. Use of its strong oxidation of cadmium, nickel-alkaline batteries, can be used as satellites, spacecraft high-energy power supply. However, there is still no consensus about the oxidation state of nickel in the oxide and the existing form of the expensive nickel oxide. Most think: trivalent nickel oxides can only exist in aqueous form, and the presence of anhydrous nickel dioxide has not been proven. This article describes the preparation of trivalent nickel oxides using electrolytic nickel chloride (II). Through thermal analysis, with chemical analysis and instrumental analysis, confirmed by the high
