Product Description
Anatase Titanium Dioxide has a lower Mohs hardness and refractive index than rutile, reflecting differences in their crystal structures. Although anatase is thermodynamically less stable than rutile, it can remain metastable under ambient conditions. At elevated temperatures, anatase may transform into rutile, with the transformation temperature depending on factors such as impurities, particle size, and processing conditions; conversion is often observed in the range of approximately 600–800°C. Optically, anatase exhibits characteristic absorption in the near-ultraviolet region, making it useful in selected optical and photocatalytic applications.
