Meaning and Definition

A mineral form of titanium dioxide, one of its naturally occurring polymorphs, characterized by its tetragonal crystal structure.

Used primarily in geological, mineralogical, and materials science contexts. As a white or clear mineral, it can be a minor ore of titanium and is of interest for its photocatalytic properties.

  • Confusing it with the more common TiO2 polymorph, rutile.

FAQ

Frequently Asked Questions

No, it is a highly specialised technical term used almost exclusively in geology, mineralogy, and materials science.

It is primarily a noun. It can be used attributively as an adjective (e.g., 'anatase phase') but does not have standard verb or adverb forms.

Both are mineral forms (polymorphs) of titanium dioxide (TiO2), but they have different crystal structures and physical properties, such as hardness and density.

The anatase form of TiO2 is a widely studied photocatalyst, useful in applications like air and water purification, self-cleaning surfaces, and solar cells.

A mineral form of titanium dioxide, one of its naturally occurring polymorphs, characterized by its tetragonal crystal structure.

Anatase is usually technical/scientific in register.

Anatase: in British English it is pronounced /ˈænəteɪz/, and in American English it is pronounced /ˈænəˌteɪs/ or /ˈænəˌteɪz/. Tap the audio buttons above to hear it.

Learning

Memory Aids

Mnemonic

Imagine an ANATomist examining a crystal under a microscope. The crystal has a TETragonal (like 'tetra' for four) structure. Anatase = ANATomist sees TETragonal crystals.
