Anatase and rutile have distinct properties that make them useful for different applications. Here are some examples of where each is used:

Anatase:

- Photocatalysis: Anatase is a highly active photocatalyst that can be used to remove organic pollutants and bacteria from water and air.
- Sunscreen: Anatase is used as a UV filter in sunscreen due to its ability to absorb and scatter UV light.
- Pigments: Anatase can be used as a pigment in white paint and coatings due to its high refractive index and brightness.

Rutile:

- Ceramics: Rutile is used as a whitening agent and flux in the production of ceramic glazes and enamels.
- Plastics: Rutile can be used as a whitening agent in plastic materials, such as PVC, to improve their color and opacity.
- Titanium metal production: Rutile is the preferred source of titanium dioxide for producing titanium metal due to its higher purity and better processing characteristics.
