Studies on Preparation and Microwave Properties of BaFe12O19/SiO2 Microcrystallite Glass Ceramics by Citrate Sol-Gel Process

Abstract

Abstract: BaFe₁₂O₁₉/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 BaFe₁₂O₁₉/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 nearoy zero.

Key words: BaFe₁₂O₁₉/SiO₂, microcrystallite, glass ceramics, sol-gel, microwave properties
