摘要： An IF7-derived iodine fluoride compound recovery method includes putting gas containing IF7 into contact with a material to be fluorinated, thereby converting the IF7 into IF5; and cooling gas containing the IF5, thereby trapping the IF5 as an IF7-derived iodine fluoride compound. The recovered IF5 may be reacted with fluorine to generate IF7, which may be reused for a semiconductor production process.

摘要： A product mixture resulting from the reaction of an anhydrous gaseous mixture of sulfur dioxide, chlorine and hydrogen fluoride in the presence of a catalyst is heated at a temperature of at least about 35.degree. C. under pressures up to about 65 psi to effect substantial conversion of undesired free chlorine in the resulting product mixture to sulfuryl chlorofluoride. The conversion of free chlorine to sulfuryl chlorofluoride allows the use of a completely anhydrous process from which uncontaminated sulfuryl fluoride and sulfuryl chlorofluoride products can readily be obtained. A method for the production of sulfuryl chlorofluoride from said gaseous mixture is also provided.

摘要： Fine-grained polygonized halide alloy bodies are formed having comparable optical properties to a single crystal halide body. Heat and force are applied to a single crystal halide to recrystallize or polygonize the halide. Room temperature grain growth observed in fine-grained pure halides is inhibited by alloying.

摘要： 1. A process for producing chlorine pentafluoride comprising the steps of continuously passing fluorine as one reactant and at least one member of the group consisting of chlorine, chlorine monofluoride and chlorine trifluoride as another reactant into a reaction chamber adjacent the lower end of the chamber, maintaining the temperature and pressure in the reaction chamber sufficiently high to effect reaction between said reactants to form gaseous chlorine pentafluoride in a mixture with gaseous fluorine; continuously passing said mixture from the reaction chamber at a place adjacent the upper end of the chamber into a condensing chamber at a place adjacent the upper end of the condensing chamber; maintaining the temperature in said condensing chamber sufficiently low to effect condensation of chlorine pentafluoride from said mixture; withdrawing condensed chlorine pentafluoride from said condensing chamber, and continuously recirculating the uncondensed gas from the condensing chamber at a place remote from the upper end of the condensing chamber to said reaction chamber at a place adjacent the lower end of the reaction chamber.
