What is the refractive index of rutile mineral form of TiO2 at 589 nm?
Titanium dioxide (TiO2) is widely used in consumer products including coatings, plastics, paper, cosmetics, and food coloring. TiO2 has a rutile stable phase in bulk and an anatase metastable phase in nano crystal form. The RI for the anatase phase is 2.56 at 589 nm [1].
What is the characteristics of 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.
What is a rutile structure?
A type of ionic crystal structure in which the anions have a hexagonal close packed arrangement with cations in half the octahedral holes. The coordination number of the anions is 6 and the coordination number of the cations is 3. compounds with this structures include TiO2, MnO2, SnO2, MgF2, and NiF2.
What is rutile crystal?
Rutile, often referred throughout history as Red Schorl,is a rare titanium oxide mineral that crystallizes in the form of grains, masses, prismatic crystals and long needle like crystals. These needle shaped crystals can be found penetrating other minerals such as Quartz, Amethyst, and Hematite.
What is the percentage of titanium in rutile?
