| Abstract: | The solid solution of yttrium aluminum garnet-yttrium iron garnet [YAIG, Y3(Al,Fe)5O12] was synthesized from the component oxides by 28 GHz-microwave irradiation. The compositions of the resulting garnets were not the same as the nominal compositions. This difference could be explained by selective coupling of chemical species with microwaves, predictable from the temperature–time profiles of each raw material under microwave irradiation. The diffusion process under microwave irradiation was discussed. |
