摘要： A sulfate process for producing titania from a titaniferous material (such as an iron-containing titaniferous material; such as ilmenite) is disclosed. The process includes precipitating titanyl sulfate from a process solution produced in the process. The titanyl sulfate precipitation step includes subjecting the precipitated titanyl sulfate to a shearing action during the course of precipitating titanyl sulfate from the process solution or after precipitation has been completed.

摘要： The invention relates to a method for producing titanium dioxide according to the sulfate process during which a titanium-containing starting material is mixed with sulfuric acid to form a reaction mixture, and this reaction mixture, in a first decomposition step, is transformed into a solid reaction mass by adding at least one other reactant whereby forming a decomposition mixture. This solid reaction mass, after passing through a ripening phase, which is referred to as the second decomposition step, and into a third decomposition step, optionally with the subsequent separation away of solids, is processed into a solution, the so-called black solution, from which titanium dioxide is then obtained in additional method steps. In at least one of the three processing steps, a gassing medium, particularly an oxygen-containing and/or nitrogen-containing gas or gas mixture, is introduced into the respective mixture, mass or solution. The aim of the invention is to provide a solution that, with a titanium starting material provided in the form of titanium slag or a mixture containing titanium slag, makes it possible to obtain a black solution having a increased proportion/content of trivalent titanium (Ti3+). To this end, the invention provides that, in the first and/or second and/or third decomposition step, an inert gas or an inert gas mixture or a gas or a gas mixture having a lower oxidation potential than air, particularly an oxygen-containing and/or nitrogen-containing gas or gas mixture is, in the form of a gassing medium, introduced, preferably blown into the respective mixture, mass or solution. This gassing medium has a, in comparison to air, lower content of oxygen, particularly an oxygen content of less than 22 % by weight, preferably less than 17 % by weight.

摘要： A sulfate process for producing titania from titaniferous material is disclosed. The process includes precipitating titanyl sulfate from leach liquors containing acidic solutions of titanyl sulfate. The process is characterised by: (a) multiple stage leaching to produce leach liquors containing acidic solutions of titanyl sulfate; (b) using depleted leach liquor from a titanyl sulfate precipitation reactor in the leach steps; and (c) controlling acid concentration in the leach steps to avoid premature hydrolysis and premature precipitation.

摘要： A method for manufacturing a highly-crystallized oxide powder, wherein an oxide powder is produced by ejecting a starting material powder comprising at least one metal element and/or semimetal element, which will become a constituent component of the oxide, into a reaction vessel together with a carrier gas through a nozzle; and heating the starting material powder at a temperature higher than the decomposition temperature or reaction temperature thereof and not lower than (Tm/2) DEG C, where Tm DEG C stands for a melting point of the oxide, in a state in which the starting material powder is dispersed in a gas phase at a concentration of not higher than 10 g/L. In the above method, the starting material powder may be mixed and dispersed in the carrier gas by using a dispersing machine prior to being ejected into the reaction vessel through a nozzle. The resultant oxide powder has a high crystallinity, a high dispersibility, and a uniform particle size, without introducing impurities thereinto, by a low-cost and simple production equipment.
