Anatase - Wikipedia
Anatase is a metastable mineral form of titanium dioxide (TiO 2) with a tetragonal crystal structure. Although colorless or white when pure, anatase in nature is usually a black solid due to impurities.

Steps on anatase TiO2(101) | Nature Materials
2006年7月16日 · We have determined the structure, energetics, and chemistry of step edges on the (101) surface of TiO2 anatase, an important photocatalytic material.
Anatase: The mineral anatase information and pictures
Anatase is a relatively uncommon yet very aesthetic form of titanium dioxide. It forms distinct and unique crystals, which are usually microscopic to very small, though a few localities have produced larger crystals. Anatase is polymorphous with …
Anatase - Mineral Properties, Photos and Occurence
2019年11月1日 · Anatase is rare and highly aesthetic form of titanium oxide, which occurs almost exclusively in Alpine environment. It's great combinations with adularia and quartz are very popular among collectors. But it also has some unique physical properties, which are used in hi-tech applications.
