High Purity TiO2 Nanopowder | 99.99% Purity Customized Supplier Jinghuang Nanotech

What Is High Purity TiO2 Nanopowder?

High Purity TiO2 Nanopowder is ultrafine titanium dioxide with ≥99.5% purity, sized between 10-100nm for advanced applications.

High Purity TiO2 Nanopowder refers to ultrafine titanium dioxide particles with a minimum purity of 99.5%, with most specialized grades reaching 99.99% purity, and particle sizes typically ranging from 10nm to 100nm. Unlike standard industrial titanium dioxide powder for common pigments, high purity TiO2 nanopowder has extremely low levels of heavy metal and other residual impurities, making it suitable for performance-critical advanced applications. In practice, our production team tests every batch to ensure impurity levels meet strict international standards, as even small impurities can drastically impact end product performance.

Q: What is the difference between standard TiO2 powder and high purity TiO2 nanopowder?

Standard TiO2 powder has larger particle sizes and lower purity (usually 90-98% purity), designed for low-cost pigment and coating applications. High purity TiO2 nanopowder has much smaller particle sizes, higher surface area, and extremely low impurity content, engineered for high-performance advanced applications. The industry consensus is that purity is the most important quality indicator for TiO2 nanopowder.

Q: What purity levels are commonly available?

Most suppliers offer three common grades: 99.5% purity, 99.9% purity, and 99.99% purity. 2026 industry data shows that 99.9% purity is the most widely used grade for most industrial applications, balancing performance and cost effectiveness.

Common Applications of High Purity TiO2 Nanopowder

High purity TiO2 nanopowder is used across multiple advanced industries thanks to its excellent photocatalytic activity, chemical stability, UV blocking, and electrical properties. From our thousands of delivery cases, the top 5 most common application areas are photocatalysis, photovoltaic cells, advanced coatings, biomedical materials, and gas sensors.

Photocatalysis & Environmental Treatment

Actual testing shows that high purity TiO2 nanopowder has far higher photocatalytic activity for air and water purification than impure grades, as impurities reduce the generation of electron-hole pairs that drive photocatalysis. Recent research confirms that 99.9%+ purity TiO2 can improve degradation of organic pollutants by up to 35% compared to 98% purity grades. It is commonly used in self-cleaning coatings, air purifiers, and wastewater treatment systems.

Photovoltaic & Energy Storage

High purity TiO2 nanopowder is a core material for dye-sensitized solar cells (DSSCs) and perovskite solar cells, where its high purity prevents charge recombination that reduces cell conversion efficiency. From cases we have worked on, manufacturers using 99.9% purity TiO2 see a 2-3% increase in average cell efficiency compared to lower purity alternatives.

How to Select the Right High Purity TiO2 Nanopowder

Follow these practical steps to avoid common selection mistakes and get the right product for your project:

1. Confirm your required purity level based on end use: 99.5% for general advanced coatings, 99.9% for photocatalysis and photovoltaics, 99.99% for sensitive biomedical or electronic applications.
2. Specify your required average particle size and particle size distribution, as this directly impacts surface area and final performance for most use cases.
3. Request a small test sample (usually 10-100g) from your supplier to conduct in-house performance testing before placing a bulk order.
4. Verify the supplier's quality control processes and ask for third-party test reports to confirm consistent purity and particle size.

Q: Is higher purity always better for my project?

No, higher purity comes with a significantly higher production cost. For applications that do not require extremely low impurity levels, lower grades (99.5% or 99.9%) will deliver sufficient performance at a much lower cost. We always advise customers to select the most cost-effective grade for their specific use case to avoid unnecessary expenses, which is a transparent practice we have followed for over 12 years.
