Properties of Rutile
Rutile is a mineral composed primarily of titanium dioxide (TiO2). It is one of the three main forms of titanium dioxide found in nature, alongside anatase and brookite. Rutile is a common accessory mineral in various types of metamorphic and igneous rocks.
The following table provides a comprehensive list of rutile properties in both SI and US customary/Imperial units at normal temperature and pressure (NTP).
