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(Fe1/2 Nb1/2)O3, from 10 to 40 mol % oflead iron tungstate Pb(Fe2/3W1/3)O3 and not more than 40 mol % of lead iron tantalatePb(Fe1/2 Ta1/2)O3 based on the total 100 mol % of a composition composed of lead ironniobate Pb(Fe1/2Nb1/2)O3, lead iron tungstate Pb(Fe2/3W1/3)O3 and lead iron tantalatePb(Fe1/2Ta1/2)O3.
