Sulfuric Acid → Titanium disulfate

Participants

Reaction Steps

A titanium ore was reacted with sulfuric acid to obtain a titanium sulfate solution, which was then subjected to thermal hydrolysis to obtain an agglomerated metatitanic acid. An aqueous slurry of 30% by weight in terms of TiO 2 was prepared therefrom and this slurry was adjusted to pH 7 with aqueous ammonia, then filtered and washed to remove sulfate. To the resulting dehydrated cake was added 35% hydrochloric acid to carry out peptization to obtain a titania sol of pH 1.5 and containing 1.5% by weight of HCl.
