Abstract: An inorganic pigment which is treated with at least one non-reactive polysiloxane of the general Formula I In general Formula I, R1 to R8 are the same or different and are selected from CmH2m+1, wherein m is ?10, and fluorinated derivatives thereof wherein at least one hydrogen atom is replaced by fluorine, C6H5, and (EO)x(PO)y and copolymers thereof, wherein EO is an oxyethylene unit, PO is an oxypropylene unit, x and y are the same or different, and x+y is in the range of 1 to 50. The at least one non-reactive polysiloxane has a viscosity in the range of 50-3000 mm2×s?1 at 25° C. The inorganic pigment treated with the at least one non-reactive polysiloxane of general Formula I has a residual moisture content of less than 1 wt-%.

Abstract: A method for granulating a particle-containing material from an industrial process includes mixing the particle-containing material in the presence of water with a material that consists of or comprises a water-absorbing and swellable organic polymer compound which is insoluble in water so as to obtain granulates.

Abstract: A composition that comprises a titanium compound, an iron compound, and a tungsten compound, wherein the titanium compound has a microcrystalline anatase structure and/or is obtained in the production of TiO2 according to the sulphate process, during hydrolysis of a solution which contains titanyl sulphate, and also in that the composition has a vanadium content, calculated as V, of less than 0.15 wt. % in relation to the solids content of the composition.

Abstract: A composition containing titanium and iron compounds, in particular decomposition residue that accumulates as a production residue after the sulphate process during the production of titanium dioxide, is used as an adsorbing agent for inorganic and organic compounds, for example compounds containing phosphorus, arsenic, antimony, sulphur, selenium, tellurium, the cyano group or heavy metal. Toxic substances and pollutants may be removed from a fluid using the adsorbing agent.

Abstract: A process for producing a coating material for coating welding electrodes and/or for producing a welding powder which can be used in an electric welding, such as in an under-powder welding, a welding powder additive, and/or a flux additive, includes obtaining a titanium-containing by-product or waste product, such as a titanium dioxide-containing material, in at least one of a production step and a production stage during a titanium dioxide production process, such as a titanium dioxide pigment production process. The titanium-containing by-product or waste product is added and/or mixed into a coating material, a welding powder, a welding powder additive, and/or a flux additive so as to obtain a titanium-containing material mixture. The titanium-containing material mixture is processed so as to provide the coating material, the welding powder, the welding powder additive, and/or the flux additive.

Abstract: The invention relates to fine-particulate zirconium titanates or lead zirconium titanates and a method for production thereof by reaction of titanium dioxide particles with a zirconium compound or a lead and zirconium compound. The titanium dioxide particles have a BET surface of more than 50 m2/g. The lead zirconium titanates can be used for the production of microelectronic components.
