摘要： This invention relates to a method of treating titania slag to increase the leachability of impurities from the slag consisting of the steps of sizing the titania slag to a particle size from 75 to 850 &mgr;m; oxidizing the sized slag particles at a temperature from about 700° C. to below about 900° C. causing the iron present in the slag to concentrate at the exposed surfaces of the slag particles and/or causing an anatase phase to stabilize in the slag, causing a major portion of the iron in the Fe(II) state to convert to the Fe(III) state, and causing the titanium in the Ti(III) state to be converted to the Ti(IV) state; and reducing the oxidized slag in a reducing atmosphere from about 700° C. to about 950° C. to convert a major portion of the iron in the Fe(III) state to the Fe(II) state. The invention also relates to a method of beneficiating titania slag to increase the TiO2 content thereof wherein the above treated slag is leached with acid.

摘要： The method is carried out in the following manner: An aqueous mixture solution containing barium chloride and titanium chloride is added into an aqueous oxalic acid solution, so that barium titanyl oxalate would be precipitated. Then the precipitates are aged, washed and filtered. The filtered barium titanyl oxalate precipitates are crushed, and dried. Then a thermal decomposition is carried out to obtain a agglomerated barium titanate powder, and this is crushed again to obtain the final barium titanate powder. In order to obtain barium titanate based powder such as Ba(Ti1−zZrz)O3, (Ba1−xCax)(Ti1−zZrz)O3, and (Ba1−x−yCaxSry)(Ti1−zZrz)O3, the desired elements (Ca, Sr, Zr and so on) are added to barium titanyl oxalate when crushed before thermal decomposition step. After thermal decomposition and crushing, the barium titanate based powder can be obtained.
