Praseodymium（Pr）Sputtering Target 

The praseodymium sputtering target is composed of high-purity praseodymium (Pr) metal. Its melting point is 935°C, boiling point is 3520°C and density is 6.77 g/cm3. Pure praseodymium metal is a soft, silvery, malleable and ductile metal, valued for its magnetic, electrical, chemical, and optical properties. It is too reactive to be found in native form, and pure praseodymium metal slowly develops a green oxide coating when exposed to air.

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.
