Thulium is a silvery white metal with the symbol Tm. It is ductile and soft and can be cut with a knife.

Thulium is relatively stable in air; thulium oxide is a light green crystal. It is a silvery white metal with a soft texture and a high vapor pressure at the melting point. Salts (divalent salts) and oxides are all light green. It is soluble in acid and can react slowly with water.

 

Applications:

✔ Thulium is often introduced into high-intensity discharge light sources in the form of high-purity halides (usually thulium bromide) to utilize the spectrum of thulium.

✔ Holmium-chromium-thulium-tri-doped yttrium aluminum garnet (Ho:Cr:Tm:YAG) is a highly efficient active laser medium material.

✔ Despite the high cost, portable X-ray devices containing thulium have begun to be used in large quantities as radiation sources in nuclear reactions

✔ Thulium has potential use value in ferrite: as a ceramic magnetic material used in microwave equipment

History:

After Mosander separated erbium and terbium from yttrium in 1842, many chemists used spectral analysis to identify them and determined that they were not pure oxides of an element, which encouraged chemists to continue to separate them.

After separating ytterbium oxide and scandium oxide from yttrium oxide, Cliff separated two new element oxides in 1879.

One of them was named thulium to commemorate Cliff's homeland (Thulia), and the element symbol was once Tu, but now it is Tm.

With the discovery of thulium and some other rare earth elements, the other half of the third stage of rare earth element discovery was completed.
