Sulfuric Acid → Titanium disulfate

Participants

Reaction Steps

Titanium-containing ores were dissolved with sulfuric acid to obtain a titanium sulfate solution. This titanium sulfate solution was hydrolyzed to obtain hydrated titanium oxide. Then, to the resultant hydrated titanium oxide were added 0.50 part by weight of ammonium phosphate, 0.30 part by weight of potassium sulfate and 0.30 part by weight of aluminum sulfate per 100 parts by weight of TiO2, followed by heating in a rotary muffle furnace for laboratory use till the temperature of the product reached 1,020° C. The thus produced titanium dioxide was cooled to room temperature and observed by means of a transmission electron microscope to find that the titanium dioxide was of anatase type having an average primary particle size of 0.13 μm.
