discovery of titanium is significant that his "parents" are just two scientists - a Briton and a German W. Gregor M. Klaproth.The first still in 1791 conducted research on the composition of the magnetic ferrous sand, which resulted in the allocated unknown up to this point metal.And in the 1795th Klaproth he conducted research in the mineral portion of rutile, and also got some metal.Ten years later, the Frenchman L. Vauquelin had himself received titanium and proved that the previous metals were identical.

Complete sample of a chemical element was obtained scientist J. Berzelius in 1825, but he then considered highly contaminated and has been able to obtain pure titanium two Dutchmen - A. baths Arkel and J. de Boer.

Titanium is the 10th of the concentration of naturally occurring chemical element among the entire periodic table.He is in the earth's crust, seawater, ultramafic rocks in the clay soil and shale.Transfer members by weathering then form the largest concentration of titanium placers.Minerals containing the chemical element itself - rutile, ilmenite, titanomagnetite, perovskite, titanite, and different indigenous titanium ore.Leader in the extraction of elements are considered, China and Russia, but it also has holdings in Ukraine, Japan, Australia, Kazakhstan, South Korea, India, Brazil and Ceylon.In 2013, world production of titanium was 4.5 million tons.

Titanium melts at a temperature of 1660 degrees Celsius, the boiling - at 3260 degrees, its density - 4,32-4,505 g / cm3.Chemical element is quite malleable and welded in an inert atmosphere, it is very tough, is prone to sticking to the cutting tool, whereby the process is carried out only by using special grease.Titanium is considered hazardous dust flashing at 400 degrees Celsius, and metal shavings fire risk.

Titanium is resistant to progressive corrosion, as well as acid and alkaline solutions.It is also known that, in the case of heating to 1200 degrees Celsius, the element begins to burn very bright white flame and forms the oxide phase.By exposure of hydrogen, aluminum and silicon is partly converted into titanium trichloride and titanium dichloride is a solid substance with a strong reducing properties.

Branches use of titanium - metallurgy and casting, where this chemical element produce high-reactors, piping, valves, medical equipment (instruments and implants) as well as many others.Another interesting fact is that the part is made of titanium monument to Yuri Gagarin in the eponymous square in Moscow.
