Key differences between Anatase and Rutile Titanium Dioxide:
- Crystal structure: Rutile is dense and stable. Anatase has a looser structure.
- Opacity and covering power: Rutile gives better hiding power due to higher refractive index.
- Weather resistance: Rutile is durable outdoors and resists UV damage. Anatase degrades under UV and may chalk or yellow.
- Photocatalytic activity: Anatase is highly active in photocatalysis; rutile is inactive and more stable as a pigment.
Abrasiveness: Anatase is softer and less abrasive, making it better for paper and textiles.
How to choose:
- Choose Rutile for outdoor paints, coatings, plastics, and long‑lasting durability.
Choose Anatase for photocatalytic applications (self‑cleaning, solar cells), paper, textiles, and indoor decorative coatings.
Titanium Dioxide Types
| Feature | Powder Form | Granules / Granular Form |
|---|---|---|
| Particle Size | Very fine, typically 0.1–0.7 μm– | Larger, typically 1–4 mm or mesh sizes (e.g., -10 to +400 mesh)– |
| Dust & Handling | High dust; requires careful handling and dust control | Low dust; easier and cleaner to handle– |
| Dispersion & Mixing | Excellent dispersion; good for liquid systems (paints, inks, coatings)– | Requires more effort to disperse; often used in dry blending or extrusion processes |
| Opacity & Hiding Power | Higher opacity and hiding power due to fine particle size– | Lower hiding power per unit weight; often used where opacity is less critical |
| Photocatalytic Activity | Higher activity; preferred for photocatalysis and UV-related applications– | Lower activity due to larger particle size and possible binder coverage– |
| Bulk Density | Lower; more volume per weight | Higher; more weight per volume, reducing storage and shipping space |
| Application Focus | Paints, coatings, inks, cosmetics, photocatalysis, paper– | Plastics, masterbatches, ceramics, glass, rubber, and processes requiring low dust– |
| Choose If | You need maximum opacity, hiding power, and dispersion in liquid systems | You want clean handling, low dust, and easy integration into dry blends or extrusion |
What is Titanium Dioxide Used for
Paints, Coatings & Inks (Most Common): Used as the primary white pigment to provide excellent whiteness, opacity, and hiding power. It improves durability and protects surfaces from UV damage.
Plastics & Rubber: Added to plastic and rubber products to enhance whiteness, opacity, and UV resistance. It also improves thermal stability and mechanical properties.
Paper Industry: Used as a filler and coating pigment to increase paper brightness, opacity, and printability, especially for high-quality paper products.
Cosmetics & Personal Care: Used in sunscreens as a physical UV blocker, and in foundations, powders, and other makeup products for coverage and whitening effects.
Photocatalytic Applications (Anatase Grade): Used in self-cleaning surfaces, air and water purification, and solar cells due to its photocatalytic activity under UV light.
Ceramics, Glass & Enamel: Used as an opacifier and pigment in ceramic glazes, glass, and enamel coatings to improve whiteness and opacity.
Food & Pharmaceutical (Food Grade): Used as a white coloring agent (E171) in some food products, confectionery, and pharmaceutical tablets.
