| Abstract: | The thermal behaviour of four coordination compounds (NH4)6Y3Fe5(C4O5H4)6(C4O5H3)6]·12H2O, (NH4)6Y3Fe5(C6O7H10)6(C6O7H9)6]·8H2O, (NH4)6Er3Fe5(C4O5H4)6(C4O5H3)6]·10H2O and (NH4)6Er3Fe5(C4O6H4)6(C4O6H3)6]·22H2O has been studied to evaluate their suitability for garnet synthesis. The thermal decomposition and the phase composition
of the resulted decomposition compounds are influenced by the nature of metallic cations (yttrium-iron or erbium-iron) and
ligand anions (malate or gluconate). |
