About TitaniumHide

Formula:
Ti
Colour:
Silver-grey
Lustre:
Metallic
Hardness:
4
Specific Gravity:
4.503 (Calculated)
Crystal System:
Hexagonal
Name:
Named for the element.
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).
