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[Zn_2(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 BaZn_1.7(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 J_m=0.425 T, J_r=0.375 T, H_cJ 100.2 kA/m, H_cB=97.1 kA/m, (BH)_max=20.4 kJ/m₃, T_c=384°C, H_A=983.6 kA/m, K_A=2.06×10⁵J/m³.
