  • Refractory ceramic mass and its use
    Patent number: 5573987
    Abstract: The present invention pertains to a refractory ceramic mass, consisting of a pure magnesia component A and a component B, which consists of granules of pure magnesia, wherein the magnesia granules of component B have a ceating consisting of a refractory material whose granule size is fine compared with that of the magnesia granules and is chemically extensively inert with respect to the magnesia granule or reacts with the magnesia granule and/or itself consists of a plurality of components that are chemically reactive with one another.

  • Refractory brick
    Patent number: 5552354
    Abstract: The present invention pertains to a refractory brick based on at least one refractory metal oxide in a particle fraction of <8 mm containing 4 to 30 wt. % of a very fine refractory fraction, prepared by firing below a temperature at which the particles of the very fine refractory fraction sinter by recrystallization with grain growth.

  • Process for producing sintered magnesia
    Patent number: 5344599
    Abstract: A process for producing coarse-grained sintered magnesia. The starting material is an active, reactive pulverulent magnesium oxide having a grain size of <0.15 mm and green compacts are formned from this magnesium oxide by pelletising on a granulating disc at a material throughput of less than 250 kg of MgO/m.sup.2 disc area and per hour, which are subsequently subjected to sinter-firing at high temperature.
    Type: Grant
