One common method to determine sulfate as TiO2 involves gravimetric analysis. In this technique, a sample containing sulfate is treated with barium chloride, resulting in the precipitation of barium sulfate. The precipitate is then filtered, dried, and weighed. The weight of the barium sulfate precipitate correlates directly with the amount of sulfate originally present in the sample. To express this as TiO2, a conversion factor based on stoichiometry is applied. This method, while straightforward, can be time-consuming and subject to errors in filtration and drying.

Manufacturers of rutile titanium dioxide employ different processes to produce this versatile pigment. The two primary methods are the sulfate process and the chloride process. In the sulfate process, ilmenite ore is treated with sulfuric acid to form titanyl sulfate solution, which is subsequently processed into titanium dioxide. This method typically results in a more opaque and durable pigment that is preferred in applications where weatherability is crucial. On the other hand, the chloride process involves treating rutile ore with chlorine gas to produce titanium tetrachloride, which is then refined and oxidized to form titanium dioxide. This method often yields a higher purity product suitable for applications requiring greater brightness and color stability.
