摘要： This invention relates to the field of materials of the photorefractive crystal. The composition of these crystals is Li1nullxNb1nullyO3: Fem, Mn, where M can be magnesium, indium, or zinc; when using q to denote the ion valence of M (qnull2 when M is Mg or Zn, and qnull3 when M is In), the values of x, y, m, and n are in the range of 0.05nullxnull0.13, 0.00nullynull0.01, 5.0null10null5nullmnull7.5null10null4, and 0.02nullqnnull0.13. This invention greatly improves the photorefractive properties of LiNbO3 crystals: makes it have a high diffraction efficiency (more than 68%), a fast response speed for photorefraction (an order of magnitude faster than iron doped LiNbO3), and a high resistance to optical scattering (the light intensity threshold to photorefractive fan scattering near two orders of magnitude larger than LiNbO3: Fe). This invention is an excellent three-dimensional optical storage material and has a vast potential market.

摘要： The present invention relates to high-purity niobium monoxide powder (NbO) produced by a process of combining a mixture of higher niobium oxides and niobium metal powder or granules; heating and reacting the compacted mixture under controlled atmosphere to achieve temperatures greater than about 1800null C., at which temperature the NbO is liquid; solidifying the liquid NbO to form a body of material; and fragmenting the body to form NbO particles suitable for application as e.g., capacitor anodes. The NbO product is unusually pure in composition and crystallography, highly dense, and can be used for capacitors and for other electronic applications. The method of production of the NbO is robust, does not require high-purity feedstock, and can reclaim value from waste streams associated with the processing of NbO electronic components.

摘要： A process for recovering vanadium contained in inorganic acid solutions by precipitating the vanadium as a solid compound of vanadium and alkali metal or monovalent cation ferricyanide. Separation is carried out electrochemically by depositing the compound on to a metal immersed in the acid solution that contains vanadium, to which a ferricyanide salt of an alkali metal or a monovalent cation has been added. If the inorganic acid present in solution is different from nitric acid, the vanadium can be also separated by direct addition of a ferricyanide salt of an alkali metal or a monovalent cation to the acid solution containing vanadium. The method described allows recovery of vanadium without modifying the initial composition of the solution, except for the concentration of the vanadium dissolved.

摘要： Niobate-based octahedral molecular sieves having significant activity for multivalent cations and a method for synthesizing such sieves are disclosed. The sieves have a net negatively charged octahedral framework, comprising niobium, oxygen, and octahedrally coordinated lower valence transition metals. The framework can be charge balanced by the occluded alkali cation from the synthesis method. The alkali cation can be exchanged for other contaminant metal ions. The ion-exchanged niobate-based octahedral molecular sieve can be backexchanged in acidic solutions to yield a solution concentrated in the contaminant metal. Alternatively, the ion-exchanged niobate-based octahedral molecular sieve can be thermally converted to a durable perovskite phase waste form.
