Dititanium trioxide

Description

Density: 4.49/cm³

Mp:2130°C

Purple powder, hexagonal structure with a lattice constant α = 0.5155nm. Oxygenated 59.5% ~ 60.8% (at).

Concentrated nitric hydrofluoric acid can be dissolved in the 40% (by mass) can be eroded, erosion but from concentrated hydrochloric acid, concentrated sulfuric acid, is not as concentrated alkali erosion, and 30% (mass) of hydrogen peroxide solution role generate micro yellow solution.

Heated in air at 250 ~ 300 ℃ into the pentoxide titanium.

1600 ℃ in vacuum heating the titanium powder and titanium dioxide mixture or 1500 ° C hydrogen reduction of titanium dioxide prepared.

Asian titanium ion itself is an excellent reducing agent.
