Beryllium - an overview | ScienceDirect Topics

Beryllium is an amphoteric metal forming the strongly acidic Be 2+ and alkaline BeO 2 2− under different conditions. Beryllium metal, carbonate, hydroxide, phosphate, and acetate dissolve in acids or alkalines. Beryllium also shows a very high affinity for oxygen, which predisposes it to the formation of insoluble phosphates (ATSDR 2002).
