The rutile and anatase forms of TiO 2 have refractive index values of 2.7 and 2.55, respectively. The oxide form of the titanium metal is TiO 2; it is naturally found as anatase, rutile or brookite minerals. Tasks (calculations) with bold text have the lowest final energy per atom output amongst all tasks with the same task type for this material. Refractive index: n = 2.561, n = 2.488: Birefringence: = 0.073: Pleochroism: Weak: References: Anatase is a metastable mineral form of titanium dioxide (TiO 2) with a tetragonal crystal structure. The application of an anatase allotropic form of TiO 2 is more commendable in DSSCs as compared to a rutile form due to its higher energy band gap of (om-TiO 2 BS) consisting of alternating high and low refractive index organized mesoporous TiO 2 (om-TiO 2) films. Titanium dioxide, also known as titanium(IV) oxide or titania / t a t e n i /, is the inorganic compound with the chemical formula TiO 2.When used as a pigment, it is called titanium white, Pigment White 6 (PW6), or CI 77891.
