What's the difference between sphene and titanium?

Sphene


Definition:

  • (n.) A mineral found usually in thin, wedge-shaped crystals of a yellow or green to black color. It is a silicate of titanium and calcium; titanite.

Example Sentences:

Titanium


Definition:

  • (n.) An elementary substance found combined in the minerals manaccanite, rutile, sphene, etc., and isolated as an infusible iron-gray amorphous powder, having a metallic luster. It burns when heated in the air. Symbol Ti. Atomic weight 48.1.
