  • Macrostructures of porous inorganic material and process for their preparation
    Patent number: 7094390
    Abstract: There is provided macrostructures of porous inorganic material which can have controlled size, shape, and/or porosity and a process for preparing the macrostructures. The macrostructures comprise a three-dimension network of particles of porous inorganic materials. The process for preparing the macrostructures involves forming an admixture containing a porous organic ion exchanger and a synthesis mixture capable of forming the porous inorganic material and then converting the synthesis mixture to the porous inorganic material. After formation of the composite material, the porous organic ion exchanger can be removed from the composite material to obtain the macrostructures.
    Type: Grant

  • Porous layers and method for production thereof by means of spin-coating
    Publication number: 20040028809
    Abstract: The present invention relates to porous layers, to a method for the production thereof and to the use of those layers in micro-electronics, in sensors, in catalytic reactions, in separation methods and in optical layers. The layers according to the invention are produced by application of a suspension of porous particles to a substrate by means of spin-coating.
