    Abstract: A method for preparing a composition including mineral particles, that is swelling TOT-TOT interlayer particles, formed by interlayering between: at least one non-swelling mineral phase formed by a stack of elementary laminae of the phyllogermanosilicate 2/1 type and of formula —(SixGe1?x) 4M3O10(OH)2—, and at least one swelling mineral phase formed by a stack of elementary laminae of the phyllogermanosilicate 2/1 type and at least one interlaminar space between two consecutive elementary laminae, the swelling mineral phase being of formula —(SixGe1?x)4M3??O10(OH)2, (M2+)??.nH2O. The composition is prepared by subjecting a gel containing silicon, germanium and metal, of chemical formula —(SixGe1?x)4M3O11,nH2O—, in the liquid state to a hydrothermal treatment which is carried out over a defined period of time and at a temperature of between 150° C. and 300° C.

  • Patent number: 7732496
    Abstract: Structurally stable and mechanically strong ceramic oxide aerogels are provided. The aerogels are cross-linked via organic polymer chains that are attached to and extend from surface-bound functional groups provided or present over the internal surfaces of a mesoporous ceramic oxide particle network via appropriate chemical reactions. The functional groups can be hydroxyl groups, which are native to ceramic oxides, or they can be non-hydroxyl functional groups that can be decorated over the internal surfaces of the ceramic oxide network. Methods of preparing such mechanically strong ceramic oxide aerogels also are provided.

  • Patent number: 7674400
    Abstract: The present invention provides a light-emitting body in which fine phosphor particles are dispersed in an oxide matrix, with the fine phosphor particles containing at least one selected from oxides and oxysulfides as a parent material. When this light-emitting body is dispersed in a resin, a resin composition having excellent transparency can be obtained. This light-emitting body can be produced by: preparing a gel through a sol-gel process in which a raw material solution containing a compound that supplies metal atoms composing the fine phosphor particles is used; and heating the gel at 400° C. or higher, for example. Preferably, the light-emitting body has a shape of a flake or fiber.

  • Publication number: 20090317619
    Abstract: The present invention describes a new class of high porosity materials with aerogel properties, based on metal oxides and their composites, possessing a high surface area and a high pore volume distributed within a specific pore diameter range. The pore distribution is monomodal and the porosity of the material is greater than 80%, conferring aerogel properties thereon while the absence of micropores (pores less than 2 nm in diameter) confers a high thermal stability to these materials. The characteristics of the product, including a low, if not zero, macroporosity, confer on the material a low dustiness compared to conventional aerogels, thus enabling them to be used effectively in production cycles.
