Sentence Examples with the word Brookite

The commonest titanium mineral is rutile or titanium dioxide, T102; anatase and brookite are crystalline allotropes.

Titanium dioxide, T102, occurs in nature as the three distinct mineral species rutile, brookite and anatase.

Rutile assumes tetragonal forms isomorphous with cassiterite, SnO 2 (and also zircon, ZrSiO 4); anatase is also tetragonal, and brookite or thorhombic. Rutile is the most stable and anatase the least, a character reflected in the decrease in density from rutile (4.2) and brookite (4.0) to anatase (3.9).
