Product Description

Product DescriptionFactory direct supply High purity metal holmium Ho Rare earth metal holmium 99.99%

Holmium is a metal element, the chemical symbol is Ho, the atomic number is 67, and the atomic weight is 164.93. The element name comes from the birthplace of the discoverer. In 1878, Solitt discovered holmium from the spectrum of erbium soil, and Clive in Sweden the following year separated holmium from erbium soil by chemical methods. The content of holmium in the earth's crust is 0.000115%, and it exists in monazite and rare earth ores along with other rare earth elements. The only natural stable isotope is holmium-165. Holmium is a silver-white metal, soft and ductile; melting point is 1474°C, boiling point is 2695°C, and density is 8.7947 g/cm3. Holmium is stable in dry air and oxidizes quickly at high temperatures; holmium oxide is the most paramagnetic substance known. Holmium compounds can be used as additives for new ferromagnetic materials; holmium iodide is used to make metal halide lamps - holmium lamps, and holmium lasers are also widely used in the medical field.Installation InstructionsHigh Purity Ho Metal 99.99 Holmium

Application

Rare earth metal holmium iron Ho≥80%, used in NdFeB additives, aluminum alloy materials and master alloys

(1) It is used as an additive for metal halide lamps. Metal halide lamps are a kind of gas discharge lamps, which are developed on the basis of high-pressure lamps. They are characterized by filling the bulb with various rare earth halides. Rare earth iodides are mainly used, which emit different spectral light colors during gas discharge. The working substance used in the holmium lamp is holmium iodide, which can obtain a higher concentration of metal atoms in the arc region, thereby greatly improving the radiation efficiency.
(2), holmium can be used as an additive of yttrium iron or yttrium aluminum garnet;
(3) The holmium-doped yttrium aluminum garnet (Ho:YAG) can emit 2μm laser, and the absorption rate of human tissue to 2μm laser is high, which is almost 3 orders of magnitude higher than that of Hd:YAG. Therefore, when the Ho:YAG laser is used for medical surgery, it can not only improve the efficiency and precision of the surgery, but also reduce the thermal damage area to a smaller size. The free beam produced by holmium crystals can remove fat without generating excessive heat, thereby reducing thermal damage to healthy tissue. It is reported that the United States uses holmium lasers to treat glaucoma, which can reduce the pain of patients' surgery. The level of China's 2μm laser crystal has reached the international level, and this laser crystal should be vigorously developed and produced.
(4) In the magnetostrictive alloy Terfenol-D, a small amount of holmium can also be added to reduce the external field required for the saturation magnetization of the alloy.
(5) In addition, holmium-doped fiber can be used to make fiber lasers, fiber amplifiers, fiber sensors and other optical communication devices, which will play a more important role in today's rapid fiber communication.Company 8 PromisesRare earth-metal holmium (high-purity nano-target semiconductor catalytic alloy electronic)
