摘要： A vapor stream from a sand chlorinator containing principally zirconium tetrachloride, hafnium tetrachloride and silicon tetrachloride contaminated with ferric chloride is purified by cooling the vapor to a temperature of about 335.degree. C. to about 600.degree. C. The cooled vapors flow through a gaseous diffusion separative barrier where a silicon tetrachloride vapor stream contaminated with metal chlorides flows from the separative barrier as a "fast" stream; ferric chloride is adsorbed by the separative barrier; and a vapor stream principally containing zirconium tetrachloride, hafnium tetrachloride and silicon tetrachloride is screened by the separative barrier.

摘要： A major cost component for zirconium alloy manufacture and fabrication is metal scrap generation during fabrication. This scrap, which has already incurred the entire process conversion cost from zircon sand to metal refining, constitutes an expensive cost to the fabrication process. The present invention teaches that these alloy scraps may be separated into their components by molten salt electrolysis using FLINAK electrolyte. The alloy components are recycled directly to the alloying process as cathodic grade metals, saving the cost of completely repeating the zircon conversion process.

摘要： This is an improved method for separating hafnium from zirconium of the type where a complex of zirconium and hafnium chlorides and phosphorus oxychloride is prepared from zirconium-hafnium chloride and the complex is introduced into a distillation column, with the improvement comprising: electrochemical breaking of the zirconium of hafnium chloride complex taken from said distillation column to separate product from the complex. The electrochemical breaking of the complex, possibly by reducing zirconium or hafnium, is done in a molten salt bath. Preferably, the molten salt in said molten salt bath consists principally of a mixture of alkali metal and alkaline earth metal chlorides and zirconium or hafnium chloride. The product can be either chloride, metal, or mixed metal and subchloride for further processing.

摘要： Scandium and yttrium present in sand is recovered from the residue pulled from sand chlorinators. The residue is digested with an acid to produce a liquid containing scandium, yttrium, sodium, calcium and at least one radioactive metal of the group consisting of radium, thorium and uranium. The metal-containing liquid is then fed through a cation exchanger. The cation exchanger is eluted with an acid to produce eluate functions containing at least partially separated metals. A first eluate fraction contains at least half of the calcium and the sodium, a second eluate fraction contains at least half of the radioactive metals, a third eluate fraction contains at least half of the scandium and a fourth eluate fraction contains at least half of the yttrium which were contained in the metal-containing feed.

摘要： This is a process for fabrication of nickel-oxide insulation on a superconductor. The process utilizes; reacting oxygen-free nickel powder with oxygen-free carbon monoxide generally at 50.degree.-75.degree. C. to produce a nickel carbonyl, separating the nickel carbonyl from reaction by-products and excess reagents by cooling the carbonyl and decanting the nickel carbonyl liquor, and contacting the carbonyl to a surface of a wire containing superconductor or superconductor precursors in an atmosphere containing a controlled amount of oxygen, with the wire at 50.degree.-800.degree. C. to produce nickel suboxide insulation on the wire. The purified nickel carbonyl and oxygen may be alternately (rather than simultaneously) introduced, to deposit a series of metallic nickel films on the wire, each of which metallic films are then oxidized to a nickel suboxide. The superconductor may be a niobium-tin superconductor, and the carbonyl contacted to wire containing unreacted niobium and tin at a wire temperature between 50.degree.-500.degree. C. to coat the wire with the nickel suboxide, and final forming of the wire done after the coating of wire and the niobium and the tin are reaction annealed after the final forming of the wire. Alternately, a wire containing unreacted niobium and tin may be formed into final form, the purified carbonyl contacted to the wire at a temperature of 500.degree.-750.degree. C. and the niobium and the tin are reaction annealed, thus the insulation and the reaction annealing can be done essentially at the same time. The superconductor may also be an oxide ceramic superconductor.

It utilizes fluidized bed chlorination of a rare earth ore (e.g. xenotime or monazite) a separation of yttrium chloride by differential condensation at 725.degree.-1200.degree.

摘要： This is a method for molten salt systems related to distillation for zirconium-hafnium separation and prevents buildup of iron chloride by electrochemically reducing iron from the molten salt to give very low levels of iron chloride in the distillation column, to reduce corrosion, improve the product and, in some cases, to allow the molten salt system to be run continuously. The improvement comprises electrochemical purification of molten salt containing zirconium-hafnium chloride either, prior to introduction of the zirconium-hafnium chloride into a distillation column, or after introduction, or both, to substantially eliminate iron chloride from the zirconium-hafnium chloride. The molten salt during the electrochemical purification consists essentially of a mixture of chlorides of alkali metals, alkaline earth metals, zirconium, hafnium, aluminum, manganese, and/or zinc.

摘要： Electrical insulation which has good dielectric strength, good radiation resistance, and good thermal resistance at temperatures of up to 500.degree. C. and, preferably up to 1700.degree. C., includes a substrate which is flexible, has the form of a filament, sheet, wrapper, tape or sleeve, and consists essentially of inorganic materials selected from the group consisting of inorganic fibers and metals, metalloids, or alloys; and at least one layer of at least one oxide of an alkoxide-forming element provided on the substrate to impregnate and/or coat same. The insulation is prepared by a process including applying a solution containing an alkoxy gel polymer, optionally additionally containing at least one inorganic material in finely divided form, to the substrate to provide a treated substrate useful as a preform when allowed to set under ambient conditions. The preform is applied to a part by, for example, wrapping, and is heated to pyrolyze the alkoxy gel polymer to its oxide and provide electrical insulation consisting essentially of inorganic materials. The application and pyrolysis steps may be repeated to build up the thickness of the at least one oxide.
