Hafnium 50mm Lucite Cube

125.00

Hafnium is rare and expensive primarily because it's so hard to get it separated from zirconium, a sister element that is chemically nearly identical. Although the two are so similar chemically hafnium is much rarer thus adding to the expense. Due to the rarity and difficulty in preparing the purified metal there are few industrial processes that see a need for hafnium, especially considering that zirconium can fill those roles in most cases. 

Here's a very substantial ~20g piece cut from a 99.95% crystal rod and polished on one side. Comes embedded in a very nice looking Lucite cube, 2 inches per side (50mm).
