Title: Study on Microwave Performance of Low-Temperature Sintered, Ba(CoTi){sub 1.5}Fe{sub 9}O{sub 19} Ferrite for Application at UHF Frequency

Abstract

M-type barium ferrite, Ba(CoTi){sub 1.5}Fe{sub 9}O{sub 19}, was synthesized via the solid-state reaction method. BBSZ, i.e., B{sub 2}O{sub 3} −Bi{sub 2}O{sub 3} −SiO{sub 2} −ZnO, was added to adjust the sintering temperature to values lower than that of silver (i.e., ∼961 °C). The phase formation characteristics, microstructure, magnetic, and microwave properties were characterized by x-ray diffraction, scanning electron microscope, vibrating sample magnetometer, and impedance analyzer, respectively. The results show that densification of samples were enhanced by increasing the amount of BBSZ with corresponding gains realized in magnetic properties. Such enhanced properties in Ba(CoTi){sub 1.5}Fe{sub 9}O{sub 19} are attributed to the low-melting point experienced as the result of BBSZ glass additives which gave rise to the stabilization of a liquid phase during sintering.
