Praseodymium Metal Cube 99.5%

When it comes to pure metal cubes, praseodymium is a special case given its affinity to oxidation. Much like an iron nail left out in the open, Pr rusts too except it does so in an off-white powdery mess that left unchecked will turn the whole object into a puffy pile of PrO2. So protecting the surface with a sealant is a must if we are to enjoy our little cube of this exotic metal.

The inch sized cubes of praseodymium come vacuum packed and must be stored in mineral oil, vacuum or an inert gas in order to preserve their integrity. The 10mm cubes will come in a glass ampule which guarantees the preservation of its metallic luster indefinitely.

Weight of each 10mm cube is 6.75±0.05g
