Abstract: A method for separating and purifying cations by ion exchange with regenerable porous glass. More specifically, the method is for decontaminating toxic waste streams such as a radioactive waste streams and concentrating the radioactive cations contained therein which comprises passage of the waste stream through an ion exchange medium of porous silicate glass or silica gel. In one embodiment, a liquid nuclear waste stream is passed through an ion exchange column containing porous silicate glass or silica gel having a plurality of .tbd.Si--O--Z groups wherein Z represents a non-radioactive cation (hydrogen, alkali metals, Group Ib metals and ammonium cations, and mixtures thereof) to displace the non-radioactive cations of the silicate glass or silica gel by the radioactive cations of the waste stream. Thereafter, the ion exchange medium is contacted with an aqueous solution of an acid to strip the radioactive cations therefrom and the stripped ion exchange medium is regenerated. The stripped ion exchange medium can be regenerated by contacting it with an aqueous basic solution of an alkali metal or ammonium ion. Additional liquid radioactive waste is contacted with the regenerated ion exchange medium to decontaminate an additional volume of liquid waste.

Abstract: A method of incorporating an additive or dopant oxide into a glass body produced by the oxidation of vaporous source material in a flame. The resultant glassy particles are deposited to form a porous preform having a uniform refractive index. During the consolidation process, the preform is subjected to an atmosphere including a drying agent which penetrates the interstices of the soot preform to simultaneously dry and dope the preform.

Abstract: An aqueous slurry comprising an intimate mixture of colloidal silica, (preferably an amorphous, precipitated, hydrated silica), caustic potash, boric acid and alumina is first prepared and then dried. The dried aggregates are thereafter crushed, calcined and rapidly quenched. It is preferred to dry the slurry in a spray drier and thereafter omit crushing after drying and to calcine the dried admixture by means of a plasma arc so that the mixture is rapidly quenched after calcination. The calcined mixture is introduced into a crusher, such as a ball mill, with a carbonaceous cellulating agent and reduced to a fine pulverulent material. The pulverulent material is then cellulated in a cellulating furnace to form cellular borosilicate bodies. Where desired, the calcined material may be utilized as a ceramic frit.

Abstract: Thermally stable, mechanically strong microporous glass articles with large pore volumes, surface areas, and varying pore sizes, and methods for making such articles are disclosed. In particle form, such as beads, the microporous glass articles are useful as catalyst supports in applications such as petroleum catalytic refiners, chemical processes and motor vehicle catalytic mufflers. The mechanical strength and the dimensional stability of the microporous glass articles at elevated temperatures can be improved if the articles are preshrunk, such as by brief exposure to high temperatures, before their intended use, and can be improved even further if treated with certain metal oxides.

Abstract: A method of producing a glass body composed of two or more oxides by the flame hydrolysis technique, for example incorporating an additive or dopant oxide in a fused silica glass body. The method comprises forming a gas stream containing vapors of a compound that will hydrolyze to a glass forming oxide, e.g., silicon tetrachloride (SiCl4), nebulizing an oxide forming compound or solution of such compound to form a mist in the nature of an aerosol, and simultaneously directing the mist and gas stream into a flame of combustible gas to form and codeposit a mixture of oxides corresponding to the vaporized and nebulized compounds.

Abstract: A method of forming an article, such as a low loss optical waveguide, by applying to a starting member a layer of glass soot to form a porous body. The porous body is then placed in a controlled environment in which a predetermined desired concentration of gases is maintained. The porous body is heated below the sintering temperature of the glass to permit entrapped gas to escape therefrom and the temperature is maintained until an equilibrium is reached between the partial pressure of the entrapped gas in the porous body and the partial pressure of the same gas in said environment. Thereafter, the porous body is further heated to at least the sintering temperature of the glass to sinter the soot particles and to form a consolidated dense member which may thereafter be formed into a desired shape while within said environment.
