Which is the best titanium dioxide?
When it comes to titanium dioxide, there isn't necessarily a single "best" option as the ideal choice can depend on the specific application and requirements. However, I can provide some general information about titanium dioxide and its common grades:
Titanium dioxide (TiO2) is a widely used white pigment and opacifier. It comes in two main crystal structures:
1. Anatase
2. Rutile
Rutile is generally considered superior for most applications due to its higher refractive index, which provides better opacity and whiteness. It's also more stable and durable than anatase.
Some factors to consider when choosing titanium dioxide:
1. Particle size
2. Surface treatment
3. Purity
4. Dispersibility
5. Photocatalytic activity (if relevant)
Popular commercial grades of titanium dioxide include:
1. DuPont Ti-Pure
2. Kronos 2190
3. Tronox CR-828
The "best" titanium dioxide will depend on your specific needs, such as:
- The intended application (e.g., paints, plastics, cosmetics, food)
- Desired properties (opacity, UV resistance, etc.)
- Cost considerations
- Environmental factors
For a precise recommendation, it's best to consult with titanium dioxide suppliers or industry experts who can evaluate your specific requirements and suggest the most suitable grade of titanium dioxide for your needs.
