ilmenite (FeTi03) an Iron ore |
Titanium Dioxide is manufactured in two crystal forms: Rutile and Anatase.
It is obtained primarily from slag by two different processes: Sulfate and
chloride. The slag is treated with sulfuric acid, and later, the resultant
titanyl sulfate is hydrolysed to form a hydrate. Both the sulfate and the
chloride process produce rutile crystalline forms, but only the sulfate
process produces anatase Titanium Dioxide, the form that is preferred for
food, drug and cosmetic use.
