Vanadium and niobium behavior in rutile as a function of ...

10-06-2014 · Vanadium occurs in multiple valence states in nature, whereas Nb is exclusively pentavalent. Both are compatible in rutile, but the relationship of V–Nb partitioning and dependence on oxygen fugacity (expressed as fO2) has not yet been systematically investigated. We acquired trace-element concentrations on rutile grains (n = 86) in nine eclogitic samples

Rutile: The titanium mineral in white paint and star ruby

Synthetic Rutile. Rutile has a very high refractive index, a strong dispersion, and an adamantine luster. These are optical properties that can produce a great gemstone, and these properties in rutile rival or exceed those of diamond. Unfortunately, natural rutile rarely has the clarity and color needed to serve as an alternative gem for diamond.
