Ti, also known as Titan, has the chemical symbol Ti and the atomic number 22. In English, it is called Titanium. The atomic mass of Ti is 47.867 and the average atomic weight is 47.867 u. Ti molecules usually have a simple structure, containing only one Titan atom. Ti can also form ions with positive charges such as Ti2+ or Ti3+.
Ti has several special physical properties. It is solid at room temperature, silver in color, and odorless. The pH of Ti is not defined because it does not dissolve in water. The chemical properties of Ti are characterized by its extremely good corrosion resistance, high-temperature tolerance, and chemical resistance.
Examples of some common chemical equations of Ti include: Ti + 2H2O -> TiO2 + 2H2(reactionwithwater), Ti + 4HCl -> TiCl4 + 2H2(reactionwithacid), Ti + O2 -> TiO2(reactionwithnonmetals).
The preparation of Ti in the laboratory is usually carried out through the thermal decomposition or electrolysis of Titan compounds. In industry, Titanium is usually produced from ilmenite or rutile minerals through the Kroll process or the Hunter process.
