Classification by type distinguishes four principal nano‑TiO₂ variants, each influencing market dynamics through performance nuances and processing requirements. Anatase‑phase particles, comprising roughly 40 % of shipments, are prized for superior photocatalytic activity, making them essential in self‑cleaning coatings and environmental remediation. Rutile‑phase, representing about 35 %, offers the highest refractive index and excellent UV stability, thereby dominating traditional pigment applications in paints and plastics. Mixed‑phase (anatase‑rutile) formulations, at 15 %, balance catalytic efficiency with optical performance, catering to hybrid uses such as UV‑curable inks. Surface‑modified nano‑TiO₂, accounting for the remaining 10 %, incorporates organic or inorganic functional groups to improve dispersion, compatibility, and safety in sensitive matrices like cosmetics and food‑contact polymers. The relative share of each type reflects the interplay between regulatory constraints, cost considerations, and end‑user performance priorities, ultimately shaping the overall market composition and growth trajectory.
