Description: Price is for ONE piece Specification: Material: Holmium Ho Metal Size: 10 X 10 X 10 mm Purity: Ho ≥ 99.9 % Weight: approx. 8.79 g Usage: Education Gifts, Science, Professional Exhibits, Eternal Collection, etc. Quantity: 1 piece Feature: It's a wonderful collection for chemical elements and natural sciences lover. We made this in cutting edge national level laboratory with rigorous process and restrictive standard. This item is not only for retail selling but bulk order is very welcome as well. Kindly notice preserving Holmium cube in dry and oxygen-deficient container is an optimize approach to prevent oxidation. We would seal it in vacuum bag before dispatch.Holmium is a chemical element with the symbol Ho and atomic number 67. Part of the lanthanide series, holmium is a rare-earth element. Holmium was discovered by Swedish chemist Per Theodor Cleve. Its oxide was first isolated from rare-earth ores in 1878. The element's name comes from Holmia, the Latin name for the city of Stockholm. Elemental holmium is a relatively soft and malleable silvery-white metal. It is too reactive to be found uncombined in nature, but when isolated, is relatively stable in dry air at room temperature. However, it reacts with water and corrodes readily and also burns in air when heated. Holmium is found in the minerals monazite and gadolinite and is usually commercially extracted from monazite using ion-exchange techniques. Its compounds in nature and in nearly all of its laboratory chemistry are trivalently oxidized, containing Ho(III) ions. Trivalent holmium ions have fluorescent properties similar to many other rare-earth ions (while yielding their own set of unique emission light lines), and thus are used in the same way as some other rare earths in certain laser and glass-colorant applications. Holmium has the highest magnetic permeability of any element and therefore is used for the polepieces of the strongest static magnets. Because holmium strongly absorbs neutrons, it is also used as a burnable poison in nuclear reactors. Holmium has the highest magnetic moment (10.6 µB) of any naturally occurring element and possesses other unusual magnetic properties. When combined with yttrium, it forms highly magnetic compounds. Holmium is paramagnetic at ambient conditions, but is ferromagnetic at temperatures below 19 K.

Items would be carried by eBay designated carrier, SpeedPAK, to most of supporting countries. Its official declaration of delivery efficiency is very similar to ePacket.ePacket via China Post: about 11-66 days to most of counties. Our average records are 7 to 21 days to North America. Parts of west coastal cities in America has the best record like just 7 to 15 days.EMS via China Post: Similar to the ePacket above.eExpress via Hong Kong Post: about 15-50 days (individual countries or even longer)All three above are national carriers in our region. Once it dispatches abroad, it would be delivered by your local national post like USPS, Canada Post, Australia Post, Royal Mail, or Deutsch Post, etc.DHL: about 3-7 days (individual countries or even longer)Note: If DHL doesn’t support service to certain areas or countries, we would switch EMS to ship your item. The EP symbol and oversea selling is possessed by Extraordinary Precision Engineering Company (HK)Thank you.
