Abstract
Experiments were carried out to investigate on the magnetic and physical properties of Ba-Zn-Li W-type hexagonal ferrites without atmosphere control. Compositions were chosen according to the formula Ba[Zn2(1-X) (LiFe)0.3Fe16O27, where X was varied between 0 and 0.6. And the effect of BaO addition after semisintering treatment on magnetic properties of Ba-Zn-Li compounds was examinend. It was found that BaO addition for Ba-Zn-Li compounds was very useful in stabilizing the W-type hexagonal. The optimum condition of making magnets and some properties ofa typical specimens are as follows: composition BaZn1.7(LiFe)0.3Fe16O27 in addition with 3wt% BaO; semisinterting condition 1275°C for 1.0h in air; sintering condition 1225°C for 0.5h in air; magnetic and physical properties are Jm=0.425 T, Jr=0.375 T, HcJ 100.2 kA/m, HcB=97.1 kA/m, (BH)max=20.4 kJ/m3, Tc=384°C, HA=983.6 kA/m, KA=2.06×105J/m3.
