Brookite

Crystal structure of brookite
Brookite from Pakistan

Brookite is the orthorhombic variant of titanium dioxide, TiO2, which occurs in four natural polymorphic forms (minerals with the same composition but different structure). The International Mineralogical Association (IMA) recognizes these four forms; the others are akaogiite (monoclinic), anatase (tetragonal) and rutile (tetragonal). Brookite is rare compared to anatase and rutile and, like these forms, it exhibits photocatalytic activity. Brookite has a larger cell volume than either anatase or rutile, with 8 TiO2 groups per unit cell, compared with 4 for anatase and 2 for rutile. Iron Fe, tantalum Ta and niobium Nb are common impurities.
