Anosovite type

Anosovite (type 1) [12065-65-5] a-Ti,0, M = 223.0070 64.1 wt.% Ti 35.9 wt.% 0 (Oxides and hydroxides) Monoclinic a = 975.2 pm = 380.2 pm c = 944.2 pm =91.55 mC32 (Z= 4) S.G. C2/m Biaxial ( )= n.a. 4900 Habit needle-hke crystals. Color blue-dark. Diaphaneity opaque. Luster metallic. Streak black. Other properties melting point 1777 C It canbe prepared by the hydrogen reduction of solid TiO at temperature around 1300 C or by mixing indomtelly stoichiometric quantities of titanium metal and titanium dioxide in an electric arc furnace under argon atmo here. This oxide is dimorphic with a rapid phase transition from semiconductor to md al occuring at rou y 120 C...
