Terbium is a chemical element; it has the symbol Tb and atomic number 65. It is a silvery-white, rare earth metal that is malleable and ductile. The ninth member of the lanthanide series, terbium is a fairly electropositive metal that reacts with water, evolving hydrogen gas.

Terbium is a rare earth element used in magnets in wind turbines and motors in electric vehicles. The United States Geological Survey (USGS) publishes annual summary reports that provide estimates of reserve and production statistics for individual …

Named after the town of Ytterby, Sweden, terbium is a soft, silvery-gray metal that can be cut with a knife. It is a rare lanthanide, and somewhat reactive, slowly reacting with air, but quickly reacting with water and acids. Terbium is used in semi-conductors and lasers. It is also used to produce the green color in color television tubes.

The most important ore are monazite, bastnasite and cerite. The main mining areas are China, USA, India, Sri Lanka, Brazil and Australia and reserves fo terbium are estimated to be around 300.000 tonnes.

2023年12月10日 · Terbium is a chemical element with the symbol Tb and atomic number 65. It is a silvery-white, rare earth metal that is malleable, ductile, and soft enough to be cut with a knife. Terbium is a member of the lanthanide series, a group of 15 similar elements between lanthanum and lutetium in the periodic table. Discovery and Naming

Geochemistry of Terbium; Goldschmidt classification: Lithophile: Tb 3+ was one of the ions least depleted from the mantle in the formation of the crust. Tb 3+ is enriched in Ca-Al-rich inclusions in meteorites relative to the composition of the solar system. Tb 3+ is concentrated in residual soils and sediments (less certainty.)

Terbium (Tb) is a chemical element included on the United States Geological Survey’s List of Critical Minerals. Tb is a lanthanide. It is the lightest of the heavy rare earth elements (REEs), excluding yttrium (Y). Note that “heavy REEs” (HREEs) are rarer than light REEs (LREEs) and thus typically more valuable.

Terbium (pronunciation: TER-bee-em) is a soft, silvery rare earth metal belonging to the Lanthanide series of elements represented by the symbol Tb [1, 2]. While the naturally occurring terbium contains one stable isotope, terbium-159, it has 36 radioactive isotopes out of which the most stable one is terbium-158 with a half-life of 180 years [3].

2022年12月1日 · Tb ore is produced in Bayan Obo ores, bastnaesite ores and ionic clays in China. Its primary products include terbium compounds. These compounds are refined to produce metal Tb. Metal Tb are further processed and manufactured into trichromatic phosphors, NdFeB magnets and others.

2025年1月21日 · Terbium is a chemical element with the symbol Tb and atomic number 65. It is a silvery-white, rare earth metal that belongs to the lanthanide series of the periodic table.
