Experimental Study on the Preparation of High-purity Nano-sized Niobium Oxide by Hydrolysis Membrane Filtration of Niobium Oxysulfate
摘要
Abstract
The hydrolysis-membrane filtration method of niobium oxysulfate is an important approach for obtaining high-purity ultrafine niobium oxide.Under certain conditions,it can achieve the goal of producing high-purity nano-sized niobium oxide.In traditional techniques,due to the complexity of raw material impurities,especially the excessive content of difficult-to-separate impurities,it becomes particularly challenging to produce high-purity nano-sized niobium oxide relying solely on a single technology.Therefore,a combined approach is needed to address technical issues such as high purity and fine particle size.For this purpose,the hydrolysis-membrane filtration method is jointly applied.Through hydrolysis-membrane filtration,the particle size is maximally controlled and the impurity content is reduced.Based on the principle that niobium and corresponding impurities have different solubilities under certain conditions,special reagents are used for dissolution,and hydrolysis-membrane filtration is employed to maximize the filtration and separation of niobium,removing impurities.By controlling the temperature during calcination,secondary agglomeration is avoided,achieving the goal of producing ultra-high-purity niobium oxide(Nb2O5>99.99%,Sb<5ppm;Si<10ppm)and nano-sized particle size.关键词
