Effect of B_2O_3 on Low Temperature Sintering Behaviors and Magnetic Properties of Yttrium Ferrite

The properties of low-temperature sintering for yttrium ferrite (Y1.05Bi0.75Ca1.2Fe4.4V0.6O12) prepared by traditional ceramic technology were studied. The results show that the appropriate addition of B2O3 can effectively decrease sintering temperature and has significant effect on the magnetic properties. With 0.025wt% B2O3 adding and sintering at 1040 ℃, the uniformity grain size and density structure are obtained, and its saturation induction intensity is 4.82×10-2 T。
