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<SUB>2(1-X)</SUB> (LiFe)<SUB>0.3</SUB>Fe<SUB>16</SUB>O<SUB>27</SUB>, 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<SUB>1.7</SUB>(LiFe)<SUB>0.3</SUB>Fe<SUB>16</SUB>O<SUB>27</SUB> 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<SUB>m</SUB>=0.425 T, J<SUB>r</SUB>=0.375 T, H<SUB>cJ</SUB> 100.2 kA/m, H<SUB>cB</SUB>=97.1 kA/m, (BH)<SUB>max</SUB>=20.4 kJ/m<SUB>3</SUB>, T<SUB>c</SUB>=384°C, H<SUB>A</SUB>=983.6 kA/m, K<SUB>A</SUB>=2.06×10<SUP>5</SUP>J/m<SUP>3</SUP>.
