Physical properties
Thulium is a naturally occurring rare metal that exists is very small amounts mixed withother rare-earths. It is a bright silvery metal that is malleable and ductile and can be cuteasily with a knife. Its melting point is so high that it is difficult to force it into a meltedstate. Its vapor pressure is also high, and thus, much of the molten thulium evaporates intothe atmosphere. Its melting point is 1,545°C, its boiling point is 2,950°C, and its density is9.32g/cm3.

Uses
Thulium is relatively scarce and expensive, which limits its commercial uses. Thulium-170,which is a radioactive isotope of thulium produced by fission in nuclear reactors, can be usedas small, portable X-ray sources. It also has limited use as an alloy metal with other metals andhas experimentally been used in lasers. (Note: Of all the isotopes of thulium, only thulium-169 is stable and nonradioactive.) Thulium(III) carbonate hydrate has specialized uses in ceramics, glass, phosphors, lasers, and also is the important dopant for fibre amplifiers. Thulium(III) carbonate hydrate has use in ferrites, ceramic magnetic materials that are used in microwave equipment. Ferrites, X-ray source.
