Praseodymium (Pr) | 25,4 x 1 mm | 99,9% (Pr/TREM)

Description

Praseodymium is a chemical element in the periodic table, with symbol Pr and atomic number 59. The name comes from the green colour of its compounds: the Greek word prásinos means ‘leek green’, didymos ‘double’ or ‘twin’. The element is classified as a rare earth metal.

Praseodymium is a soft, silver-white, paramagnetic metal that belongs to the lanthanide family of rare earth metals. It is slightly more resistant to corrosion in air than europium, lanthanum or cerium, but tends to form a green oxide layer that flakes off in air. At 798°C, the hexagonal α-Pr transforms into the body-centred cubic β-Pr.

* This is a recommendation based on our experience with these materials in our sputtering guns. Rates are based on non-bonded targets and are material specific. Bonded targets should be operated at lower power to avoid bonding failure. Bonded targets should be operated at 20 watts/square inch or less depending on the material.
