Titanium Dioxide - Titania ( TiO2) - AZoM.com

From Goodfellow Jan 11 2002. Titania TiO2 exists in a number of crystalline forms the most important of which are anatase and rutile. Pure titanium dioxide does not occur in nature but is derived from ilmenite or leuxocene ores. It is also readily mined in one of the purest forms, rutile beach sand. These ores are the principal raw materials ...
