Allotropes of plutonium
Six or seven different forms that pure plutonium metal can take / From Wikipedia, the free encyclopedia
Plutonium occurs in a variety of allotropes, even at ambient pressure. These allotropes differ widely in crystal structure and density; the α and δ allotropes differ in density by more than 25% at constant pressure.
