Abstract: The invention relates to a complete method for producing pure silicon that is suitable for use as solar-grade silicon, comprising the reduction of a silicon oxide, purified by acidic precipitation from an aqueous solution of a silicon oxide dissolved in an aqueous phase, using one or more pure carbon sources, the purified silicon oxide being obtained, in particular, by the precipitation of a silicon oxide dissolved in an aqueous phase in an acidifier. The invention also relates to a formulation containing an activator and to a device for producing silicon, a reactor and electrodes.

Abstract: Carbon black with an aggregate size distribution ratio ((d 9 0-d 1 0)/d 5 0) of = 1.1, is new. Independent claims are included for: (1) preparation of the carbon black; and (2) device for executing the above process comprising a burner and a cooling surface against which the flame is directed, where the cooling takes place through a self-constricting gap, which has a height/width ratio of 1-100 mm, where the width is related to the upper edge of the gap and is 0.5-10 mm and the flow velocity at the narrowest point of the gap is 10-200 m/s.

Abstract: Aqueous carbon black dispersions, wherein the carbon black dispersions contain no wetting agent and contain at least one ozone-oxidised carbon black. Said dispersions are produced by dispersing ozone-oxidised carbon black and the other constituents in water. Said dispersions may be used for the production of inks, printing inks and water-based lacquer systems.

Abstract: An oxidatively aftertreated carbon black has a content of volatile constituents of more than 10 wt. %, based on its total weight, and the ratio of its CTAB surface area to the iodine adsorption number is greater than 2 m2/mg. The carbon black may be a channel black oxidatively aftertreated with ozone. The carbon black according to the invention is used preferably as pigment carbon black for the production of water-based paints, printing inks and as inks for mechanical and manual recording and drawing instruments. The combination of properties imparts to the carbon black an excellent dispersibility in water-based binder systems. The paints, printing inks and printer inks produced from this carbon black have an outstanding stability in storage.
