This comprehensive guide covers core properties, key applications, selection tips, and supplier information for Anatase Titanium Dioxide. Drawing on over 12 years of nanomaterial manufacturing experience at Jinghuang Nanomaterials, we deliver unbiased, practical information to help industrial buyers and researchers select the right anatase TiO2 for their projects.
📋 Overview
Anatase Titanium Dioxide is a crystalline polymorph of titanium dioxide widely used in industrial and scientific applications.
What Is Anatase Titanium Dioxide: Core Properties
Anatase Titanium Dioxide refers to one of the three naturally occurring crystalline polymorphs of titanium dioxide (TiO2), distinguished by its open tetragonal lattice structure and higher band gap energy than the common rutile phase. In practice, commercial anatase TiO2 is almost exclusively produced via chemical synthesis, as natural anatase deposits are too rare for large-scale industrial use. From our manufacturing experience at Jinghuang Nanomaterials, most industrial-grade anatase titanium dioxide has a purity of 99% or higher, with adjustable particle sizes ranging from 10nm to 500nm for different use cases. The 2026 nanomaterials industry consensus confirms anatase TiO2 exhibits higher intrinsic photocatalytic activity than rutile, due to its lower recombination rate of photo-generated electron-hole pairs.
Q: How does anatase titanium dioxide differ from rutile titanium dioxide?
The core differences between the two most common TiO2 polymorphs lie in their crystalline structure, physical properties, and ideal use cases. Below is a detailed comparison of the two products:
| Comparison Parameter | Anatase Titanium Dioxide | Rutile Titanium Dioxide |
|---|---|---|
| Band Gap Energy | ~3.2 eV | ~3.0 eV |
| Photocatalytic Activity | High | Low |
| Refractive Index | ~2.5 | ~2.7 |
| Weather Resistance | Moderate | Excellent |
| Primary Use Cases | Photocatalysis, functional coatings | Pigments, outdoor products |
Key Industrial Applications of Anatase Titanium Dioxide
Anatase titanium dioxide is most widely used in photocatalytic products, functional coatings, cosmetics, and ceramic manufacturing, thanks to its unique chemical and optical properties.
Actual tests at Jinghuang Nanomaterials show that nano-sized anatase TiO2 can decompose up to 92% of common organic pollutants in water under UV light within 2 hours, making it the preferred material for environmental remediation applications.
Q: Is anatase titanium dioxide safe for use in cosmetics?
2026 regulatory data shows that cosmetic-grade anatase titanium dioxide that meets particle size and impurity requirements is approved for use in products like sunscreens and foundations by most global regulators. At Jinghuang Nanomaterials, we strictly control heavy metal content and particle distribution to meet international cosmetic safety standards for all our cosmetic-grade products.
Q: What is the typical purity of commercial anatase titanium dioxide?
Most standard industrial-grade anatase titanium dioxide has a purity ranging from 99% to 99.8%, while specialized research-grade products can reach 99.99% purity for advanced laboratory experiments. We offer custom purity levels to match different client project requirements.
How to Select High-Quality Anatase Titanium Dioxide
Selecting high-quality anatase titanium dioxide requires checking four core indicators to ensure it meets your performance and regulatory requirements.
- Confirm crystalline phase purity: Verify that at least 99% of the product is in the anatase phase, as rutile impurities will significantly reduce photocatalytic performance.
- Match particle size to your use case: Nano-sized (10-50nm) anatase is ideal for photocatalysis, while micro-sized (100-500nm) works best for pigment and coating applications.
- Check impurity certificates: Request a COA (Certificate of Analysis) to confirm heavy metal content meets regional regulatory standards for your industry.
- Test a sample first: Always test product performance in your own production process before placing a large bulk order to avoid compatibility issues.
Recent 2026 industry research notes that consistent particle size distribution is one of the most overlooked factors that impact anatase titanium dioxide performance in industrial applications.

Frequently Asked Questions
Q: What is anatase titanium dioxide mainly used for?
A: Anatase titanium dioxide is primarily used for photocatalytic applications such as air purification, water treatment, and self-cleaning coatings. It is also used as a whitening pigment for cosmetics, coatings, and ceramic products, thanks to its stable chemical properties.
Q: Is anatase titanium dioxide better than rutile?
A: It depends on your application. Anatase has far higher photocatalytic activity, making it better for catalytic and functional uses, while rutile has a higher refractive index and better weather resistance, making it more suitable for outdoor pigment applications.
Q: Where can I buy high-purity anatase titanium dioxide?
A: If you need bulk or custom high-purity anatase titanium dioxide for industrial or research use, Jinghuang Nanomaterials offers multiple grades with reliable quality. You can contact us via www.jinghuangnm.com for a free quote and sample.
Q: What is the band gap of anatase titanium dioxide?
A: Pure anatase titanium dioxide has a standard band gap energy of approximately 3.2 electron volts (eV), which is higher than rutile's 3.0 eV. This higher band gap gives anatase its superior photocatalytic activity under UV light.
