Chloride TiO₂

Chloride titanium dioxide is a premium-grade TiO₂ pigment produced through the chloride process — one of the two principal industrial manufacturing routes for titanium dioxide. In this process, titanium-bearing ores, typically high-grade rutile or synthetic rutile, are reacted with chlorine gas at high temperatures to form titanium tetrachloride (TiCl₄). This intermediate is then purified through fractional distillation and subsequently oxidized at extreme temperatures to yield a highly pure, fine-particle rutile TiO₂ pigment.

Compared to the sulfate process, the chloride route produces titanium dioxide with a higher degree of chemical purity, tighter particle size distribution, and superior optical properties. The resulting product is almost exclusively rutile in crystal form — the crystal structure renowned for its exceptional refractive index, durability, and UV resistance. Chloride-process TiO₂ has become the industry standard for applications where performance, consistency, and longevity are the primary purchasing criteria.
