Holmium Sputtering Targets (Ho)

Holmium is a chemical element with the symbol Ho and atomic number 67. Part of the lanthanide series, holmium, is a rare earth element. Swedish chemist Per Theodor Cleve discovered holmium. Its oxide was first isolated from rare earth ores in 1878, and the element was named after 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 will also burn in the atmosphere when heated.
