Effect of synthesis conditions on the formation of Y3-xLaxFe5-yO12+δ/La1-xYxFe1-yO3 composite
Glass-like composite materials with high oxygen conductivity values were obtained by growing from a homogeneous melt by the method of non-melting zone melting. A complex architecture of the composite is observed: the main phase is highly defective in cationic and anionic sublattices Y3-xLaxFe5-yO12+...

| description | Glass-like composite materials with high oxygen conductivity values were obtained by growing from a homogeneous melt by the method of non-melting zone melting. A complex architecture of the composite is observed: the main phase is highly defective in cationic and anionic sublattices Y3-xLaxFe5-yO12+δ with a garnet structure, inside which the germination of filamentous crystals La1-xYxFe1-yO3 with a perovskite structure is observed. The effect of the method of synthesis of polycrystalline precursors used as raw materials for the production of the melt on the formation of the structure of composites La1-xYxFe1-yO3/Y3-xLaxFe5-yO12+δ is investigated. The composite obtained from the precursor formed by the formate method contains ~87 mol.% of the main phase.The composite obtained from the precursor formed by the self-propagating high-temperature synthesis is ~76 mol.% of the garnet phase. The obtained composites have a certain growth direction of the main phase Y3-xLaxFe5-yO12+δ <100>. |
