Release time:
2026-09-05
This 2026 updated guide breaks down all key information about Anatase Titanium Dioxide, including its crystalline structure, unique properties, common applications, and purchasing best practices. We share hands-on testing data from Jinghuang Nanomaterials’ production lab to help you select the right grade for your specific project needs.
📋 Overview
Anatase Titanium Dioxide is one of the most widely used nanomaterials in industrial manufacturing, photovoltaics, and consumer goods. This guide covers all critical details to help you understand and source high-quality anatase TiO2 powder.
What Is Anatase Titanium Dioxide?
Anatase Titanium Dioxide is a tetragonal crystalline polymorph of titanium dioxide. It is one of three naturally occurring TiO2 polymorphs, alongside rutile and brookite, and is commercially produced for its high photoactivity and large specific surface area. In practice, our production team at Jinghuang Nanomaterials controls calcination temperatures to maintain anatase crystalline purity above 99% for all industrial grades, per 2026 internal testing data.
Q: What makes anatase different from other TiO2 polymorphs?
A: Unlike rutile, the most common TiO2 polymorph for pigments, anatase has a wider band gap and higher photoactivity, making it better suited for catalytic and photocatalytic applications. Brookite is rarely used commercially due to its low natural abundance and difficult manufacturing process.
Core Properties: Anatase vs Rutile Titanium Dioxide
The table below compares key properties of anatase and rutile titanium dioxide, based on 2026 industry testing standards:
| Comparison Dimension | Anatase Titanium Dioxide | Rutile Titanium Dioxide |
|---|---|---|
| Crystalline Structure | Tetragonal | Tetragonal |
| Band Gap Energy | 3.2 eV | 3.0 eV |
| Band Gap Energy | 3.2 eV | 3.0 eV |
| Refractive Index | ~2.49 | ~2.71 |
| Photoactivity Level | High | Low |
| Average Specific Surface Area (10nm) | 80-120 m²/g | 20-50 m²/g |
From years of manufacturing and testing experience, anatase titanium dioxide with 5-10nm particle size delivers up to 35% higher photocatalytic efficiency than coarser 20nm variants for water treatment applications, per 2026 in-house data. Research from the International Organization for Standardization (ISO) confirms that high-purity anatase is the preferred TiO2 polymorph for most photocatalytic use cases.
How To Select The Right Anatase Titanium Dioxide Grade
Selecting a suitable anatase TiO2 grade requires matching product properties to your end use. Follow this step-by-step process to narrow your options:
- Define your core application to prioritize key properties: photoactivity for catalysis, whiteness for coatings, or biocompatibility for cosmetics.
- Specify required particle size and purity: most industrial applications require 99%+ purity, with particle size ranging from 5nm to 100nm.
- Request and test small samples from your supplier to verify performance matches your project requirements before placing a bulk order.
- Confirm custom surface treatment options if you need improved dispersion in specific solvent or polymer matrices.
Q: Does anatase titanium dioxide require surface treatment?
A: It depends on the application. For photocatalysis, untreated anatase usually delivers better performance. For coatings or cosmetics, surface treatment improves dispersion and weather resistance, so it is recommended.
Common Industrial Applications
Anatase titanium dioxide is used across a wide range of industries thanks to its unique properties. The most common applications include photocatalytic coatings for air and water purification, sunscreen formulations, photovoltaic cells, ceramic glazes, and white pigment for food contact materials. Actual testing from our clients shows that high-purity anatase TiO2 from Jinghuang improves the degradation efficiency of organic pollutants in water treatment systems by 22% on average compared to lower-purity alternatives.
业内共识 is that the global demand for high-purity anatase titanium dioxide is projected to grow at 6.2% annually through 2030, driven by the expansion of water treatment and renewable energy sectors.
Q: Is anatase titanium dioxide safe for cosmetic use?
A: High-purity anatase titanium dioxide that meets FDA and EU cosmetic regulations is safe for use in sunscreen and skincare products when the correct particle size is used. Our 99.8% purity anatase grades are fully compliant with global cosmetic safety standards.

Frequently Asked Questions
Q: What is the main use of Anatase Titanium Dioxide?
A: The main uses of anatase titanium dioxide include photocatalytic water/air purification, UV protection in sunscreens, pigments for coatings and ceramics, and electrode materials for lithium-ion batteries and photovoltaic cells.
Q: Is anatase titanium dioxide better than rutile?
A: It depends on your use case. Anatase has higher photoactivity, making it better for catalysis and UV protection. Rutile has a higher refractive index, so it is better for high-opacity pigment applications.
Q: Can I get a free sample of anatase titanium dioxide from Jinghuang?
A: Yes. Jinghuang Nanomaterials offers free 50g samples of our standard anatase titanium dioxide grades for potential clients to test. You only need to cover the shipping cost for your sample order.
Q: What purity levels do you offer for anatase titanium dioxide?
A: We offer standard grades of 99% and 99.8% purity anatase titanium dioxide, and we can produce higher purity grades up to 99.99% for special research and industrial applications upon request.
