Web7 mei 2015 · Since lithium, beryllium, and boron are small atoms, they are more likely to be formed in cosmic ray collisions. Lithium provides an interesting special case. Of the two stable isotopes of lithium, 7 Li is more abundant. We know from the Big Bang theory that some of it was created shortly after the Big Bang. WebDaarbij ontstaat metallisch beryllium uit een mengsel van gesmolten beryllium- en natriumfluoride (NaBeF 3) met een positieve pool (anode) van koolstof en een negatieve pool (kathode) van nikkel. Uit berylliumfloride is ook beryllium te verkrijgen door reductie met magnesium bij 900 ºC. Een derde mogelijkheid biedt het chlorideproces.
