Overview
High-purity titanium dioxide (TiO2) is a refined form of titanium dioxide, prized for its exceptional brightness and opacity. It is produced through either the sulfate or chloride process, with the latter yielding higher purity grades. As a versatile inorganic compound, it serves as a critical raw material in industries requiring superior whiteness and durability. The global demand for high-purity TiO2 is driven by its unmatched light-scattering properties and stability under extreme conditions. Its rutile and anatase crystal forms cater to specific applications, with rutile being more thermally stable. Manufacturers often apply surface treatments to enhance dispersibility in different matrices.
Physical and Chemical Properties
High-purity TiO2 exhibits a high refractive index (2.7 for rutile), making it one of the most effective white pigments. Its chemical inertness ensures compatibility with most binders and resins, while its UV absorption properties protect substrates from degradation. The material is thermally stable up to 1800°C in inert atmospheres. Particle size distribution (typically 0.2–0.3 µm) directly impacts opacity and gloss in end products. Advanced grades may include alumina or silica coatings to reduce photocatalytic activity, which can degrade organic substrates. Its insolubility in water and solvents necessitates proper dispersion techniques during formulation.
Main Applications
In coatings, high-purity TiO2 provides exceptional hiding power and weatherability, making it ideal for architectural and automotive paints. Plastics manufacturers use it to achieve brilliant whites in PVC, polyolefins, and engineering resins while improving UV resistance. The paper industry relies on TiO2 for high-quality printing surfaces and opacity in lightweight papers. Cosmetic applications include sunscreens (as a physical UV blocker) and makeup pigments. Specialty grades are employed in ceramics, catalysts, and even food contact materials (where permitted). Emerging uses include photocatalytic coatings for air purification and self-cleaning surfaces.
Safety and Storage
While TiO2 is generally regarded as non-toxic, inhalation of fine dust should be avoided due to potential respiratory irritation. OSHA recommends a permissible exposure limit (PEL) of 15 mg/m³ for total particulate. Nano-sized TiO2 requires additional handling precautions pending regulatory classifications. Storage requires protection from moisture absorption, which can cause caking. Use sealed containers in well-ventilated areas away from strong acids or reducing agents. Bulk shipments typically use 25-kg multi-layer paper bags or 1-ton super sacks with moisture barriers.
B2B Procurement Guide
When sourcing high-purity TiO2, prioritize suppliers with ISO 9001 certification and batch-specific certificates of analysis. Key specifications to verify include TiO2 content (≥99%), trace metal impurities (especially Fe, Cr, V), and oil absorption values. For coatings applications, assess dispersibility through Hegman grind tests. Consider regional supply chains—Chinese producers dominate volume production, while European and American suppliers often specialize in niche grades. Negotiate pricing based on quarterly contracts to mitigate price volatility linked to titanium ore and energy costs. Sample testing under actual production conditions is strongly advised.
