KRONOS Special Grades
Anatase is one of three mineral forms of titanium dioxide and is always found as small, isolated and sharply developed crystals. It has a steeper pyramid with a longer vertical axis than other forms of titanium dioxide, which is how it earned its name in 1801 from the Greek word anatasis, meaning “extension.”
There are important differences between the physical characteristics of anatase and another common form of TiO2, rutile. The former is less hard (5.5-6 vs. 6-6.5 Mohs) and less dense (specific gravity about 3.9 g·cm-3 vs. 4.2 g·cm-3).
