The titan — light silver - white metal. Exists in two crystal modifications: α - Ti with a hexagonal plotnoupakovanny lattice (a=2, 951 Å; with =4, 679 Å; z=2; spatial group C6mmc), β - Ti with cubic objyomnotsentrirovanny packing (a=3, 269 Å; z=2; spatial group Im3m), transition temperature α ↔β 883 °C, ΔH transition 3, 8 kJ/mol. The melting point of 1660±20 °C, a boiling point of 3260 °C, density α - Ti and β - Ti is respectively equal 4, 505 (20 °C) and 4, 32 (900 °C) to g/cm ³ , nuclear density 5, 71×1022 at/cm ³ [the source is not specified 664 days]. It is plastic, cooks in the inert atmosphere. Specific resistance 0, 42 mky · m at 20 °C
Has high viscosity, when machining it is inclined to sticking to the cutting tool and therefore drawing special coverings on the tool, various greasings is required.
At a usual temperature becomes covered by the protective passivating TiO2 oxide film, thanks to it korrozionnostoyek in the majority of Wednesdays (except alkaline).
Titanic dust has property to blow up. Temperature of flash is 400 °C.
