Beryllium carbonate is a chemical compound with the chemical formula BeCO₃. There are three forms reported, anhydrous, a tetrahydrate and basic beryllium carbonate. The anhydrous form is reported to be unstable, decomposing to BeO and carbon dioxide, and requiring storage under CO₂.^[1] The tetrahydrate is said to be formed when CO₂ is bubbled through a solution of Be(OH)₂ and is also reported to be similarly unstable.^[2] Basic beryllium carbonate is a mixed salt, which can be prepared by the reaction of beryllium sulfate and ammonium carbonate, and contains both carbonate and hydroxide ions, with formula Be₂CO₃(OH)₂.^[3] It is believed that in the older literature this is probably what was referred to as beryllium carbonate.^[3]
