【摘要】 对Ｗ型六角晶系铁氧体吸收剂复介电常数进行了研究，通过实验着重研究配方中Ｆｅ＿２Ｏ＿３的掺入量对介电常数的影响，研究发现，在分子式正分配方附近复介电常数ε的实部值ε＇与虚部ε″值随Ｆｅ＿２Ｏ＿３的掺入量增加而升高，对材料中出现二价铁离子Ｆｅ￣（＋＋）对介电常数的影响以及介电常数随频率的变化进行了分析。更多还原

【Abstract】 Complex permittivity of W-type hexagonal microwave ferrite absorbent was studied inthis paper. Effect of Fe₂O₃ additive value on complexpermittivity was mainly investigated.It was foundout that real permittivity ε’and imaginarypermittivity ε″increased with increasing Fe₂O₃additive value nearby precise prescription . Effect ofFe￣（++） apeared in absorbent on complex permittivityand changing of complex permittlvity with increasing frequency were analyzed.更多还原
