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.
