文摘

LiZrZn ferrite materials (Li_0.47Zr_0.11Zn_0.27Fe_2.15O₄) were synthesized at 900 °C with different contents of LBBS (Li₂O-B₂O₃-Bi₂O₃-SiO₂) glass. We characterized and analyzed the variation in phase formation, structure, sintering shrinkage percentage and magnetic properties of samples along with the content of LBBS glass. A spinel phase could be formed at 900 °C with LBBS glass, which allowed them to be co-fired with silver in LTCF application. The saturation magnetization M_s increased first with increase of LBBS glass, and then decreased. The coercivity H_c decreased first from 51.1 to 44 Oe, and then increased to 47 Oe. The real part of magnetic permeability increased from about 21 to 29 in a range frequency of 1 MHz ~10 MHz, and magnetic loss kept a low value of about 0.05.
