| Herkunft des Namen: | griechisch: titanos (Titans) |
| Beschreibung: | Shiny, dark-gray metal. Ninth most abundant element in the earth's crust (5700 ppm). It can be highly polished, and is relatively immune to tarnishing. |
| Entdeckt von: | William Gregor |
| Jahr: | 1791 |
| Ort: | England |
| Quelle(n): | Usually occurs in the minerals ilmenite (FeTiO3) or rutile (TiO2). Also in Titaniferous magnetite, titanite (CaTiSiO5), and iron ores. Pure metal produced by heating TiO2 with C and Cl2 to produce TiCl4 then heated with Mg gas in Ar atmosphere. |
| Verwendung(en): | Since it is strong and resists acids it is used in many alloys. Titanium dioxide (TiO2), a white pigment that covers surfaces very well, is used in paint, rubber, paper and many others. |
