Studies on Preparation and Microwave Properties of BaFe_(12)O_(19)/SiO_2 Microcrystallite Glass Ceramics by Citrate Sol-Gel Process |

| Abstract: | BaFe12Ol9/SiO2 microcrystallite glass ceramics were prepared by citrate so1-gel pro- cess; The complex dielectric constant and complex permeability dispersion were investigated in 100MHz-6GHz range. The results obtained show those conditions such as Ba/Fe, sintering tem- perature have a close effect on the synthesis of BaFel2Ol9/SiO2 microcrystallite glass ceramics; the complex dielectric constant and complex permeability will decrease as the measuring frequency increasing, and maximum dielectric loss is 0.40, but magnetic loss nearly zero. |
