About Native Titanium
Formula:
Ti
Colour:
Silver-grey
Lustre:
Metallic
Hardness:
4
Specific Gravity:
4.503 (Calculated)
Crystal System:
Hexagonal
Name:
Titanium, the metallic element, was named in 1795 by Prussian Chemist Klaproth after the Titans of Greek mythology, having investigated titanium oxide from rutile.
As is the habit with most native elements, the mineral name is shared with the element.
As is the habit with most native elements, the mineral name is shared with the element.
Type Locality:
Dimorph of:
Two forms of native titanium have been found - one, found in granite, crystallizes in the hexagonal system, the other as minute inclusions in garnet from an ultrahigh-pressure metamorphic complex crystallizes in the tetragonal system (see Tetragonal Titanium).
Hexagonal α-Titanium was described from fumaroles of the Northern Break of Great Fissure Tolbachik Eruption of 1975 in 1992.
Considered doubtful for a longer time, finally approved in 2010 (IMA 2010-044).
