W. Gunsser et al., PREPARATION AND STRUCTURAL-PROPERTIES OF AMORPHOUS AND POLYCRYSTALLINE GD3CRXGA5-XO12 (X = 0, 1, 2), Solid state ionics, 63-5, 1993, pp. 666-671
The preparation of amorphous mixed oxides with rare earth garnet stoic
hiometry by co-precipitation of the hydroxides is described. By means
of DTA measurements, X-ray diffraction and absorption as well as by el
ectron microscopy changes in structure and physical properties during
the annealing process in a temperature range up to 1400-degrees-C are
controlled.
