摘要：
A sol-gel method based on in situ generation of mixed-metal chelates by complexing metal ions with ethane-1,2-diol in aqueous media has been elaborated to prepare lanthanide-ion containing garnets, Gd3Al5O12 (GAG) and La3Al5O12 (LAG). XRD patterns of the powders sintered at 1 000 degrees C revealed the formation of monophasic GAG. However, LAG does not form under the same experimental conditions. The phase composition of the samples was characterised by IR spectroscopy. Microstructural features of the polycrystalline garnets were studied by SEM.
