稀土元素
描述
Holmium comprises approximately 1.4 parts per million (ppm) of the Earth’s crust by mass. Consequently, it is positioned as the 56th most abundant element in the Earth’s crust. Holmium does not exist in its pure form in nature. It is commonly observed in association with various mineral constituents, such as gadolinite, monazite, and other minerals that belong to the rare-earth category.
特征
Holmium is a bright silver lustrous metal. It is soft and corrosion resistant element. At standard temperature and pressure, it is stable in dry air. It oxidizes quickly in moist air and high temperature to form yellowish oxide. In its oxides form, its color changes take place dramatically due to its sharp absorption characteristics as it tarnished yellow to fiery orange red. It is paramagnetic at ambient temperature and ferromagnetic below 19 K. Holmium chemical symbol is Ho with atomic number 67. Its atomic weight is 164.93. Holmium melting point is 1461OC and boiling point is 2600OC. Its density at room temperature is about 8.79 g/cm3.
Holmium possesses a relatively high atomic weight of approximately 164.93032 atomic mass units (u). It is a silver-white, lustrous metal that is soft and malleable. Holmium is classified as a rare earth element due to its occurrence in the Earth’s crust, although it is not as abundant as some other elements in this group. One of the notable properties of holmium is its magnetic nature.
应用和使用
Holmium alloys are used as a magnetic flux concentrator to create the strongest artificially generated magnetic fields. It is also used in nuclear reactors for nuclear control rods. Holmium oxide is used as yellow gas colouring. Holmium is used to • Quantum Computers • Magnets • Lasers • Calibration • Treatments.
