摘要：A high frequency wave absorbing ceramics can be used, for example, as an EMIpreventive filter for interrupting high frequency waves intruding into electronic circuits.The high frequency wave absorbing ceramics are composed of a ternary composition
from 50 to 80 mol% of lead iron niobate Pb(Fe Nb)O, from 10 to 40 mol % of lead irontungstate Pb(FeW)O and not more than 0 mol % of lead iron tantalate Pb(Fe Ta)O basedon the total 100 mol % of a composition composed of lead iron niobate Pb(FeNb)O, leadiron tungstate Pb(FeW)O and lead iron tantalate Pb(FeTa)O.
