Titanium dioxide exists in three crystalline phases: rutile, anatase, and brookite.
1. Rutile is the most stable and common form, having a tetragonal crystal structure. It has high refractive index and is often used in pigment applications and photocatalysis.
2. Anatase is another widely preferred form due to its higher photocatalytic activity compared to rutile. It has an octahedral crystal structure.
3. Brookite is the least common form of titanium dioxide, and it is not widely used due to its difficult synthesis and transformation to other phases. It has an orthorhombic crystal structure.
Both anatase and rutile can be converted to brookite at high temperatures. The specific phases and their proportions can significantly influence the material's optical and chemical properties.
