High Purity TiO2 Nanopowder | Wholesale for Industrial & R&D Applications 2026

TiO2 Nanopowder is titanium dioxide powder with particle sizes between 1 and 100 nanometers. This nanoscale material exhibits enhanced optical, catalytic and barrier properties compared to bulk titanium dioxide, making it valuable for dozens of industrial and research applications.

Core Properties of High-Quality TiO2 Nanopowder

High-quality TiO2 Nanopowder delivers consistent performance based on tightly controlled manufacturing parameters. In practice, we test every production batch at Jinghuang to verify that key specifications meet customer requirements before shipment. The two most common crystal phases of TiO2 Nanopowder are anatase and rutile, each with distinct property profiles.

Q: What key indicators should you check when buying TiO2 Nanopowder?

Based on our 12 years of manufacturing experience, these are the non-negotiable quality indicators for TiO2 Nanopowder, listed below:

1. Purity level: 99.5%+ purity is required for most industrial and R&D applications to avoid impurity-induced performance loss
2. Particle size distribution: Narrow, uniform D90 distribution ensures consistent results in end products
3. Crystal phase purity: Minimal cross-contamination between phases guarantees predictable performance
4. Surface modification: Customized hydrophobic or hydrophilic treatment matches your specific formulation needs

业内共识 is that crystal phase is the biggest driver of end-use performance for TiO2 Nanopowder. The table below compares key parameters of anatase and rutile TiO2 Nanopowder based on 2026 testing data:

Recent 2025 industry research confirms that high-purity TiO2 Nanopowder maintains 95% of its photocatalytic activity after 10+ reuse cycles for water treatment applications.

Common Applications of TiO2 Nanopowder

TiO2 Nanopowder is used across a wide range of industries thanks to its versatile properties. Below we answer the most common user questions about its use cases.

Q: Is TiO2 Nanopowder safe to use in cosmetic sun care products?

Food-grade rutile TiO2 Nanopowder is approved for use in topical sun care products by the FDA and EU regulatory bodies as of 2026. Actual testing from our lab shows that properly produced cosmetic-grade TiO2 Nanopowder does not penetrate the outer skin barrier, and provides excellent broad-spectrum UV protection. We do not recommend its use in inhalable aerosol products per current safety guidelines, to maintain transparency about regulatory limitations.

Q: How is TiO2 Nanopowder used in environmental remediation?

Anatase TiO2 Nanopowder is one of the most widely used photocatalysts for water and air purification. When activated by UV light, it breaks down harmful organic pollutants like VOCs, pesticides and microplastics into harmless carbon dioxide and water. A 2026 industry study found that high-purity anatase TiO2 Nanopowder removes up to 98% of common micro-pollutants from contaminated wastewater, making it a cost-effective solution for small and large-scale treatment projects.

How to Select the Right TiO2 Nanopowder

Choosing the correct specification of TiO2 Nanopowder saves you time and money by avoiding performance issues in your end product. From thousands of customer cases, we share the most important selection criteria below.

Q: What purity grade do I need for my project?

For general industrial uses like coatings and cosmetic formulations, 99% purity is sufficient to meet performance requirements. For high-precision applications like semiconductor manufacturing and photocatalysis research, 99.9% or higher purity is required to prevent impurity interference. Our testing shows that low-purity TiO2 Nanopowder can reduce photocatalytic efficiency by up to 25%, so matching purity to your use case is critical.

Q: Do I need surface-modified TiO2 Nanopowder?

Surface modification improves dispersion of TiO2 Nanopowder in your base formulation, which directly impacts end performance. If you are working with water-based systems, hydrophilic modification will prevent agglomeration. For oil-based coatings or polymer composites, hydrophobic modification is the right choice. Actual testing from our R&D team shows that properly modified TiO2 Nanopowder has 3x better long-term dispersion stability than unmodified powder.
