Serial number of elements: 22

Element symbols: Ti

Element name: titanium

Elements of atomic weight: 47.87

Element type: metal

Found: Gregory Goyle found Year: 1791

Discovery process:
1791, Britain's grid column Gore, in the study of black magnetic sand, found that there is a new element, titanium.

Element Description:
       Has a metallic luster, ductility. Density of 4.5 g / cm 3. Melting point of 1660 ± 10 ℃. Boiling point 3287 ℃. Valence +2, +3 and +4. The ionization energy of 6.82 electron volts. The main characteristics of the titanium density, mechanical strength, and easy to process. The plasticity of the titanium is mainly dependent on the purity. The more pure titanium, the greater plasticity. Good corrosion resistance, from the atmosphere and seawater. At room temperature, will not be as dilute hydrochloric acid, sulfuric acid, nitric acid or dilute alkali solution corrosion; only hydrofluoric acid, before its role in the hot concentrated hydrochloric acid, concentrated sulfuric acid, etc..

Element Source:
      Titanium is rare in abundance in the earth's crust seventh, 0.42%. For smelting titanium mineral ilmenite (FeTiO3), rutile (TiO2) and perovskite. The ore treated volatile titanium tetrachloride, and then magnesium reduction to obtain a titanium.

Elements Uses:
      A large number of titanium and titanium alloys used in the aerospace industry, known as "space metal"; increasingly wide range of applications in the shipbuilding industry, the chemical industry, the manufacture of mechanical parts, telecommunications equipment, carbide, etc..

Elements of auxiliary information:
      Titanium ore rutile TiO2 and ilmenite FeTiO3, its discovery is also coming from these two ore analysis. As early as 1791 in England southwestern tip of Cornwall (Cornwall) County the parish priest door pull Chan (Menacan), grid tired Gore, also a scientist, and analysis produced a black ore in his Diocese, is today The ilmenite ore found a new metal material and named menacenite to. Three years later, in 1795, Klaproth analyzed Hungary bui Nick (Boinik) produced rutile, recognize that it is a new metal oxide has the characteristics of resistance to acid, alkali solution, to borrow the earth in Greek mythology Titans Protoss Titans, the first generation of sons named the metal titanium, element symbols as Ti. Two years later, Klaproth confirmed grid tired Gower discovered menacenite titanium.

For an acid, an alkali, the titanium having a strong corrosion resistance, has become an important material in the chemical production.

Titanium generally think that is a rare metal, in fact, it is quite content in the earth's crust, than the common metal zinc, copper, tin, etc., even than chlorine, phosphorus.
