Overview
Titanium dioxide (TiO2) white particles are one of the most important white pigments used industrially. The compound occurs naturally in several mineral forms, with rutile and anatase being the most commercially significant. As a pigment, titanium dioxide is valued for its exceptional brightness and very high refractive index - higher than diamond in some forms. This makes it highly effective at scattering visible light, resulting in superior opacity and whiteness compared to alternative materials.
Physical and Chemical Properties
TiO2 exists in three main crystal structures: rutile (the most stable form), anatase, and brookite. The rutile form is preferred for most industrial applications due to its higher refractive index and greater chemical stability. The material is thermally stable with a melting point above 1800°C and shows remarkable resistance to both acidic and basic environments. Its photocatalytic properties, particularly in the anatase form, make it useful in self-cleaning surfaces and air purification systems.
Main Applications
About 60% of global TiO2 production is used in paints, coatings and plastics. In these applications, it provides opacity, durability and protection against UV degradation. The food industry uses titanium dioxide as a whitening agent (E171), though this application has faced increasing regulatory scrutiny. Other significant uses include sunscreen formulations (where it acts as a physical UV blocker), paper manufacturing, and as a catalyst support in chemical processes.
Safety and Storage
While TiO2 is generally considered non-toxic, fine particulate forms may pose inhalation hazards. Proper ventilation and respiratory protection are recommended when handling powder forms. Storage requires protection from moisture and contamination. Bulk quantities should be stored in sealed containers away from strong acids and reducing agents. The material is non-flammable but may increase the burning rate of combustible materials.
B2B Procurement Guide
Industrial buyers should specify the required crystal form (rutile or anatase), particle size distribution, and surface treatment. For coatings applications, oil absorption values and dispersibility are critical quality parameters. Consider supply chain reliability and technical support when selecting suppliers. Many manufacturers offer grade-specific technical data sheets and application support. Large-volume contracts often include price adjustment clauses linked to raw material (ilmenite or rutile ore) costs.
