Holmium - Element information, properties and uses

Holmium is a chemical element with the symbol Ho and atomic number 67. It is a rare-earth element and the eleventh member of the lanthanide series. It is a relatively soft, silvery, fairly corrosion-resistant and malleable metal. Like a lot of other lanthanides, holmium is too reactive to be found in native form, … See more Physical properties Holmium is the eleventh member of the lanthanide series. In the periodic table, it appears between the lanthanides dysprosium to its left and erbium to its right, and above the See more Holmium (Holmia, Latin name for Stockholm) was discovered by Jacques-Louis Soret and Marc Delafontaine in 1878 who noticed the aberrant spectrographic absorption bands of the then-unknown element (they called it "Element X"). As well, See more Magnets Holmium has the highest magnetic strength of any element, and therefore is used to create the strongest artificially generated magnetic fields, when placed within high-strength magnets as a magnetic pole piece … See more The price of 1 kilogram of Holmium Oxide 99.5% (FOB China in RMB/Kg) is given by the Institute of Rare Earths Elements and Strategic Metals as … See more Oxides and chalcogenides Holmium(III) oxide is the only oxide of holmium.
