    摘要： Granules based on pyrogenically prepared silicon dioxide doped with aluminum oxide by means of an aerosol, which granules have the characteristic data: mean particle diameter: from 10 to 150 &mgr;m BET surface area: from 25 to 100 m2/g pH value: from 3 to 6 tamped density: from 400 to 1200 g/l They are produced by dispersing in water pyrogenically prepared silicon dioxide doped with aluminum oxide by means of an aerosol, spray drying the dispersion, and optionally carrying out tempering and/or silanization. In the silanized form, the granules have the following characteristic data: mean particle diameter: from 10 to 160 &mgr;m BET surface area: from 15 to 100 m2/g pH value: from 3 to 9 tamped density: from 400 to 1200 g/l carbon content: from 0.3 to 12.0 wt. % The granules are used inter alia as a catalyst and catalyst support, in cosmetics for sun-protection formulations, in silicone rubber, in toner powders, in paints and inks, as grinding and polishing agents, as a raw material for the production of glass and ceramics.

    摘要： The present invention relates to a novel process for producing ceramic materials, in particular refractory materials having a reduced relative density. In particular, the invention relates to a process for producing light, refractory materials having non-contiguous pores based on shaped and unshaped materials. These materials can be used as working lining in high-temperature applications. The process is based on the production of spherical, closed and isolated pores in the microstructure of the material. The pores having a pore diameter which can be set in a targeted manner are generated by use of polymer particles, in particular polymethacrylates, in particular polymers or copolymers prepared by means of suspension polymerization, as pore formers which can be burnt out. The polymers or copolymers are present in the form of small spheres having a defined diameter. The introduction of isolated spherical pores allows the production of ceramic materials having a sometimes significantly reduced relative density and improved corrosion resistance and better mechanical strength compared to the prior art. The specific, closed pore system at the same time contributes to reducing the thermal conductivity of the ceramic materials. In addition, the novel process has the advantage that there is no risk of formation of undesirable black cores, even in the production of thick-walled ceramic products.
