Metamorphosis (Physical Characteristics of Uranium Hexafluoride)

The Uranium Hexafluoride phase diagram is investigated. An experimental setup is shown to look at the gas, liquid, and solid phases at various temperatures and pressures. This information is used to understand what happens inside a DUF6 storage cylinder.
