What are the three forms of TiO2?
There are three main types of titanium dioxide (TiO2) based on crystal structure: rutile, anatase, and brookite.
Rutile TiO2 is the most stable and the most widely used form, commonly found in coatings, plastics, inks, and masterbatches due to its excellent opacity and durability.
Anatase TiO2 is less stable but known for its photocatalytic properties, making it suitable for photocatalysis, paper, and specialty applications.
Brookite TiO2 is the least common form and is rarely used in commercial products, appearing mainly in laboratory and research settings.
All three share the same chemical composition, but their crystal structures give them different properties. In practice, rutile dominates industrial use, anatase serves functional applications, and brookite is largely limited to research.
