Titanium monoxide properties: golden yellow powder. Do not dissolve in water, nitric acid, soluble in sulfuric acid, partially dissolved in dilute hydrochloric acid to form trivalent titanium ions and produce hydrogen. The chemical properties are not stable, and the titanium dioxide is heated in a carbon electric furnace or reduced by a reducing agent such as zinc, magnesium or hydrogen. Used in the manufacture of titanate semiconductors.
Titanium monoxide contains 52% to 54% (atoms) of oxygen. Body-centered cubic structure. The density is 4.888 g/cm3. The temperature of 1750 ° C. Soluble in 40% by mass of hydrofluoric acid. Easily oxidized by concentrated concentrated sulfuric acid, concentrated hydrochloric acid and concentrated nitric acid. It can also be concentrated by concentrated alkali. A yellow solution is formed with 30% by mass of hydrogen peroxide. It is a strong reducing agent. When heated by air, it is converted to titanium oxynitride at 150 to 200 °C. Titanium oxide can be obtained by heating a mixture of titanium metal and titanium dioxide at 1600 ° C in a vacuum, reducing titanium dioxide by hydrogen at 2000 ° C, or reducing titanium dioxide by magnesium at 1000 ° C. Titanium oxide has an oxygen or titanium vacancy property and can be used as an electronic material.
Titanium monoxide can be used as a catalyst for ethylene polymerization, and can also be used for preparing titanate semiconductors and for making light-shielding films, black cosmetics, and the like.
