About TistariteHide

Formula:
Ti3+2O3
Crystal System:
Trigonal
Member of:
Name:
Name is derived from the word "star", and the composition "Ti", implying that this new mineral is likely a condensate among the first solids formed in the solar system at the birth of our star.
Hematite Group. One of just a few currently known phases with essential trivalent titanium, including grossmanite, 'UM1971-21-SiO:AlCaMgTi' and 'UM1978-08-O:AlCaCrFeMgTi'.

Compare 'UM1987-04-O:Ti'.
