General Characteristics

Tulium is a chemical element in group III of the periodic table of D. I. Mendeleev, where it is called Tm. Its atomic weight is 168.9. It is a malleable silvery metal of the lanthanoid series, a fairly rare element. Its content in the lithosphere is 2.^7-10-5%. Euxenite, xenotime, and monazite are the richest in tulium. The honor of tulium discovery belongs to two scientists. In 1879 Swedish chemist Kleve succeeded in separating tulium oxide from a mixture of oxides. In its pure form it was obtained in 1911 by Richardson, who determined its main physical and chemical properties. It is named after the legendary northern island of Thule.

Physicochemical properties

It belongs to the group of heavy lanthanides, its density is 9.32 g/cm3 , it is malleable, very technologically advanced metal, the melting point reaches almost 1545 ° C, the boiling point 1947 ° C. It is readily soluble in inorganic acids.

Uses

Tulium borate is widely used in nuclear power. In the production of lasers, tulium ions are used to excite radiation in the infrared part of the spectrum with a wavelength of 1910 nm. Vapors of this metal are used in tunable-frequency lasers. It is a valuable thermoelectric material. It is also used in magnetic storage media. Tulium monotelluride has high efficiency and considerable e.d.s. It is the basis of thermal transducers, and it regulates the properties of lead telluride semiconductors. Tulium-170 isotope is used in metal flaw detectors and in portable X-ray units. Its use as fuel for nuclear boilers is being developed.
