Sulfuric Acid → Titanium disulfate

Participants

Reaction Steps

A titanium-containing ore was dissolved in sulfuric acid to obtain a titanium sulfate solution. This titanium sulfate solution was hydrolyzed to give hydrated titanium oxide. Then, to 100 parts by weight (as reduced to TiO2) of the resultant hydrated titanium oxide were added 0.50 parts by weight of ammonium phosphate, 0.30 parts by weight of potassium sulfate, and 0.30 parts by weight of aluminum sulfate, followed by heating in a rotary muffle furnace for laboratory use till the temperature of the product reached 1020° C. The thus produced titanium dioxide fine particles were cooled to room temperature and observed by means of a transmission electron microscopic photograph to confirm that the titanium dioxide was of anatase type having an average primary particle size of 0.13 μm.
