Chemical compound
Erbium(III) carbonate is anerbium compound with thechemical formula Er2 (CO3 )3 .
Erbium carbonate can be made by the thermal decomposition oferbium(III) trichloroacetate which can be made by the reaction betweenerbium(III) oxide andtrichloroacetic acid .[ 1]
Er2 O3 + 6 CCl3 CO2 H → 2 Er(CCl3 CO2 )3 + 3 H2 O 2 Er(CCl3 CO2 )3 → Er2 (CO3 )3 + side products Alternatively, the poor solubility of erbium carbonate in water can be used to precipitate it from an aqueous solution of erbium(III) ions andcarbonate ions.[citation needed
2 Er3+ + 3 CO3 2− → Er2 (CO3 )3 Erbium carbonate thermally decomposes toerbium(III) oxide upon heating.
Er2 (CO3 )3 → Er2 O3 + 3 CO2 This can be used to producenano particles of erbium oxide as erbium carbonate can be selectively precipitated into particles with an average size of 36 nm.[ 3] [ 4]
It has a low solubility in water but dissolves in acids likeperchloric acid .[ 1]
It reacts with thechelator thenoyltrifluoroacetone by losing the three carbonate ions.[ 5]
