The europium sputtering target is a sputtering target composed of high-purity metal europium (Eu). It has a melting point of 822°C and a density of 5.24 g/cm3. Europium is the most reactive lanthanide by far, having to be stored under an inert fluid to protect it from atmospheric oxygen or moisture. Europium is also the softest lanthanide, as it can be dented with a fingernail and easily cut with a knife. When oxidation is removed a shiny-white metal is visible.
Storage and clean.
praseodymium sputtering target must be protected by paraffin oil from oxidation.
1.Prepare 500 ml of acetone or ethanol liquid, open the package of the target, take the target out by tweezers ,and put the target into the acetone or ethanol liquid, and clean it by ultrasonic, until the target surface is clean.
2.If you don’t have a ultrasonic cleaner, you can put the target into the acetone or ethanol liquid, and use a soft brush to gently scrub the target surface, until the surface is clean.
3.Then do the flash drying and put the target into the magnetron sputtering system.
4.Pls keep the used target in paraffin oil if you don’t use it.
