This article explores the stability of titanium dioxide (TiO₂) under sunlight, highlighting the differences between its rutile and anatase forms. Rutile TiO₂ is known for its exceptional durability and resistance to UV degradation, making it ideal for outdoor applications like paints. In contrast, anatase TiO₂ exhibits strong photocatalytic properties that can break down organic materials around it when exposed to UV light but does not degrade itself. This duality makes TiO₂ valuable in various industries, from coatings to environmental applications. Understanding these characteristics helps manufacturers select the appropriate form of TiO₂ for their specific needs while addressing concerns about chalking in paints and potential health risks associated with prolonged exposure.
