Zirconium Sputtering Target

Zirconium (Zr) is a silver metal with a density of 6.52 g/cm3. Zr has a tiny neutron absorption cross-section, and a relatively high melting point (1855 °C or 3371 °F), making zirconium an excellent material for nuclear power rods. Zirconium sponge and crystal bars are the raw materials to make sputtering targets. Although Zr sponge is cheap and has low purity, it contains a high oxygen content. Zirconium crystal bars have a higher cost and purity, making them ideal materials for sputtering targets.
