(n.) A mineral consisting of titanic oxide, and hence identical with rutile and octahedrite in composition, but crystallizing in the orthorhombic system.
Example Sentences:
Rutile
Definition:
(n.) A mineral usually of a reddish brown color, and brilliant metallic adamantine luster, occurring in tetragonal crystals. In composition it is titanium dioxide, like octahedrite and brookite.
Example Sentences:
(1) Anatase and rutile are titanium dioxides (TiO2) with different crystal lattices.
(2) The hydrogen bonding ability of the surfaces of these rutiles were compared with inert rutile and quartz.
(3) Only two, both synthetic rutiles, were found to be active.
(4) These results suggested that perovskite and rutile existed at the interface between hydroxyapatite and titanium after plasma-spraying and made hydroxyapatite to bond tightly to the titanium.
(5) Biological studies of two titanium dioxide polymorphs, rutile and anatase, have produced conflicting results.
(6) The binding properties of the active rutile have been found to be consistent with those properties associated with biologically active quartz.
(7) Rutile samples containing trace amounts of nickel or chromium had an activity similar to that of pure rutile.
