Rutile: The titanium mineral in white paint and star ruby

Rutile and a number of other metallic ore minerals are mined together from sedimentary deposits known as "heavy mineral sands". These sediments are derived from the weathering of igneous and metamorphic rocks that contain abundant tiny grains of high-specific-gravity minerals such as rutile, ilmenite, anatase, brookite, leucoxene, perovskite, and titanite (also known as sphene).

2017/3/6A unique single-crystal rutile (TiO2) structure, which does not conform to Pauling's third rule, was prepared by high-temperature ultracentrifugation (0.4 106 G at 400 C). The anisotropy (a/c) of the tetragonal phase increased by 2%. The (Ti−Oa)/(Ti−Ob) and Os Get price

Rutile

The rutile crystal structure is tetragonal, comprising octahedrally coordinated cations and three-fold coordinated anions. The most widely studied rutile materials are TiO 2 and SnO 2 . Both materials have wide-ranging technological uses for which surface interactions play a dominant role, including catalysis ( Berry, 1982; Wold, 1993 ) and chemical sensor (Gpel et al., 1988; Semancik and Get price

What is the Rutile structure?

2014/7/9It is, in fact, a cell known as tetragonal, where although each of the corner angles are 90 degrees, one of the cell lengths can be different – making for an oblong box with square cross-section. The 'original' rutile structure is actually titanium dioxide, or TiO 2, and is a mineral commonly found in metamorphic rocks . Get price

Tetragonal crystal system — Wikipedia Republished //

In crystallography, the tetragonal crystal system is one of the 7 crystal systems. Tetragonal crystal lattices result from stretching a cubic lattice along one of its lattice vectors, so that the cube becomes a rectangular prism with a square base (a by a) and height (c, which is different from a).
