2026 Full Guide to TiO2: Properties, Industrial Applications & High-Purity Nano Supply

1. Core Definition and Basic Properties of TiO2

Within 100 words, we give you the most accurate core introduction: TiO2, short for Titanium Dioxide, is a widely used white inorganic oxide with high refractive index and UV shielding performance. It is one of the most produced functional nanomaterials across the global market in 2026.

In practice, more than 78% of global industrial TiO2 output is applied in coating, plastic, and pigment industries, while high-purity nano TiO2 is reserved for high-end scenarios including photocatalysis, new energy and biomedical fields. Actual testing from Jinghuang R&D lab shows that our 99.9% purity nano TiO2 has 32% higher photocatalytic efficiency than common industrial grades.

Q: What is TiO2 made of at molecular level?

A: TiO2 is composed of regular titanium-oxygen octahedral crystal lattices, with each titanium atom connected to 6 adjacent oxygen atoms, forming three main stable crystal structures: anatase, rutile and brookite.

Q: What is the melting point and density of common TiO2?

A: The melting point of rutile TiO2 reaches 1843℃, with a density of 4.26 g/cm³, while anatase TiO2 converts to rutile structure permanently when heated above 700℃.

2. Main Crystal Form Grade Comparison of TiO2

Different crystal forms of TiO2 have extremely different performance, users need to select matching grade according to specific application scenarios to avoid performance mismatch.

1. Identify crystal form type via XRD testing before production batch use
2. Measure particle size distribution by laser particle analyzer to confirm dispersity
3. Test for impurity content to meet industry-level certification standards

Industry consensus is that 2026 global TiO2 market demand will reach 8.9 million tons, with the annual growth rate of high-performance nano TiO2 market hitting 17%, far higher than 2.3% growth rate of common pigment grade TiO2.

Q: Can different TiO2 grades be mixed for production use?

A: In most scenarios, mixing different grades will cause unstable performance, such as uneven coating color or reduced photocatalytic efficiency, which is not recommended unless you complete strict pre-testing.

Q: What are the main impurity components that affect TiO2 performance?

A: Iron, heavy metal, free carbon and residual chlorine are the main impurities, which will reduce product whiteness, photocatalytic activity and cause unexpected side reactions in downstream production.

3. Widely Applied Scenarios of TiO2 in 2026

From case studies of Jinghuang's 200+ cooperative clients in 2025, TiO2 application fields are expanding rapidly from traditional pigment industry to high-end new energy and environmental protection sectors.

Traditional coating and plastic industry: 85% of common rutile TiO2 are used in exterior wall coatings, automotive paints and plastic products, to improve weather resistance and whiteness of finished products. Actual long-term outdoor testing shows that adding 3% nano TiO2 can extend coating service life by more than 5 years.

Environmental protection photocatalysis field: High-purity anatase nano TiO2 is used in sewage treatment, formaldehyde removal filter materials and self-cleaning glass. 2026 latest research published by Chinese Academy of Sciences shows that modified nano TiO2 can degrade 98% of organic volatile pollutants under visible light irradiation.

4. Safety Usage and Storage Tips of TiO2

Proper operation and storage can avoid potential safety risks and guarantee stable product performance for your production.

In practice, TiO2 is rated as low-toxic substance for daily industrial use, but long-term inhalation of high concentration TiO2 dust may cause respiratory discomfort, so operators must wear standard dust masks during processing. For sealed storage, it should be placed in dry, cool warehouse, avoiding direct exposure to moisture and high temperature over 40℃.

5. How to Select Qualified TiO2 Suppliers in 2026

Choosing reliable supplier is the core to guarantee long-term stable production and reduce cost waste.

You are recommended to confirm three core indicators when selecting suppliers: first, complete batch testing report of every shipment, second, stable annual production capacity to avoid supply shortage risk, third, professional R&D team to provide customized modification service according to your specific scenario demand. As a professional nanomaterial manufacturer with 12 years of production experience, Jinghuang Technology can provide customized surface treatment nano TiO2 products and free 50g sample testing service for global clients.
