Dissolution of Uranium Tetrafluoride (open access)

Dissolution of Uranium Tetrafluoride

"Five new dissolution processes for uranium tetrafluoride are discussed-the NH4OH-H2O2 method, the H2SC4 - (NH4)2S2O8 method, the AlCl3 method, the NaAlcl method, and the Al (NO3)3.9E2O method. It is concluded that NaAlCl4 and Al(NO3)3.9H2O are preferable to the other agents, especially with regard to rate of dissolution and ease of manipulation."

The Metallurgy of Beryllium (open access)

The Metallurgy of Beryllium

The following report describes a study by the M.I.T. Metallurgical Project to pursue the quest of producing ductile beryllium, as beryllium has a relatively high strength, good corrosion resistance to water and air and a melting point of about 1230 C, features that make it a great potential value among being one of the most effective of all materials for slowing down neutrons with little tendency to absorb them.
