Patent number: 11566328Abstract: Aqueous solutions of halogenides (oxyhalides) of zirconium and hafnium (M) with values of ?=X/M near one, for X=Cl, Br and I form amorphous solids or glasses, designated as M,X, in contrast to important crystalline oxyhalide end members with ?=2 (designated as MOX). The present disclosure describes methods for producing amorphous thin films comprising halogenides upon evaporation, and provides some measured physical properties, with attention to compositions for ?<2. The value of a below which only glasses are formed is about one for oxychlorides and oxybromides of both Zr and Hf. The chemical formulas for all the halogenide thin films prepared as noted above can be written as a function of the single parameter ?, according to M(OH)4-?X?.(4?-1)H2O. This is valid for e.g., crystalline zirconium oxychloride octahydrate, and for the glassy solids found for ?<2 and down to the onset of hydrolysis, ??0.5.Type: GrantFiled: June 17, 2020Date of Patent: January 31, 2023Assignee: Oregon State UniversityInventors: Jennie M.

Patent number: 6358484Abstract: A process for providing a zirconium basic sulfate includes providing a zirconium oxychloride solution, and then dialyzing the solution against a liquid selected from water and an aqueous solution across at least one anion exchange membrane to provide a dialyzate and diffusate. The dialyzate includes at least 90 percent of the zirconium ions of the zirconium oxychloride chloride solution and has a total acidity that is lower than the original zirconium oxychloride solution. A precipitate including zirconium basic sulfate may be formed from at least a portion of the diffusate. The zirconium oxychloride solution may be provided, for example, by dissolving zirconium tetrachloride in one of water and a hydrochloric acid solution. A material including zirconium basic sulfate produced by the process of the invention also is disclosed.Type: GrantFiled: March 31, 2000Date of Patent: March 19, 2002Assignee: ATI Properties, Inc.Inventor: James A.

Patent number: 5569440Abstract: An improved carbochlorination process for the production of volatile metal chlorides is disclosed. When chlorine gas contacts a metal oxide or a mixed metal oxide in a reaction zone in the presence of carbon at elevated temperatures, an undesirable carbochlorination residue forms containing carbon in the reaction zone. After the build-up of a carbochlorination residue in the reaction zone occurs, the volume of the carbochlorination residue in the reaction zone is reduced by periodically introducing just chlorine and metal oxide or mixed metal oxide reactants into the reaction zone without introducing any additional carbon. These components react with a portion of the carbon in the carbochlorination residue so as to reduce the amount of the residue.Type: GrantFiled: September 14, 1994Date of Patent: October 29, 1996Assignee: Teledyne Industries, Inc.Inventor: James A. Sommers
