TL;DR: In this paper, a method for preparing aluminum oxide and other products by aluminum-containing materials of bauxite, alunite, nepheline, fly ash, kaolin, coal gangue and clay is described.
Abstract: The invention relates to a method for preparing aluminum oxide and other products by aluminum-containing materials of bauxite, alunite, nepheline, fly ash, kaolin, coal gangue and clay. The method comprises the following steps: (1) crushing and grinding an aluminum-containing material, carrying out mixing and baking for the treated aluminum-containing material and ammonium bisulfate; (2) carryingout dissolution and filtering for the baked clinker to obtain a crude ammonium aluminum sulfate solution and aluminum extracting residue; (3) carrying out an iron precipitating treatment for the ammonium aluminum sulfate solution with the concentration more than 1 g/L by adopting a jarosite method, then carrying out an iron precipitating treatment by a goethite method, carrying out an aluminum precipitating treatment for the resulting solution, carrying out calcination for the resulting aluminium hydroxide to prepare aluminum oxide; (4) carrying out an iron precipitating treatment for the ammonium aluminum sulfate solution with the concentration less than 1 g/L by adopting the goethite method, and carrying out an aluminum precipitating treatment to prepare aluminum oxide, or adopting a recrystallization method to carry out purification, adopting a reaction of the ammonium aluminum sulfate crystal and a ammonium carbonate solution to precipitate the aluminum to obtain ammonium aluminumcarbonate, carrying out calcination for the ammonium aluminum carbonate, and adopting a Bayer method to treat the calcined ammonium aluminum carbonate to prepare sandy aluminum oxide; (5) washing anddrying the aluminum extracting residue, wherein the dried aluminum extracting residue is adopted as the silicon dioxide product.

TL;DR: In this article, a process for the coating of glass microspheres with an aluminium hydroxide is described, which comprises the hydrothermal treatment of a suspension of complexed Al3+-ions with glass micro-spheres.
Abstract: A process for the coating of glass microspheres with an aluminium hydroxide is described which comprises the hydrothermal treatment of a suspension of complexed Al3+-ions with glass microspheres. The aluminium hydroxide coated glass microspheres can be applied in the production of light weight glass-reinforced plastic materials e.g. for use in mass transportation.

TL;DR: In this paper, a fire-proofing mixture consisting of a mixture of a water-eliminating hydroxide, especially aluminium hydroxides, with a magnesia binder was proposed.
Abstract: of EP0485867The invention relates to a fire-proofing composition comprising a mixture of a water-eliminating hydroxide, especially aluminium hydroxide, with a magnesia binder, in particular a mixture of magnesium oxide and magnesium sulphate. This fire-proofing composition can be used for the manufacture of fire-proofing elements - for example as a fire-protection layer (3) in inserts (1) of fire-proof doors - and for direct fire-inhibiting filling of hollow profiles of metal, which are used, for example, as a wall part or drawer part of a fire-proof cabinet or cassette. The fire-proofing agent according to the invention especially permits easy and inexpensive manufacture of fire-proofing elements based on mineral wool.
