Dielectric ceramic for microwave applications
摘要:
A dielectric ceramic for microwave applications is comprised of:X BaO.Y TiO.sub.2.Z {(Sm.sub.2 O.sub.3).sub.1-W1-W2 (La.sub.2 O.sub.3).sub.W1 (Nd.sub.2 O.sub.3).sub.W2 }where X, Y, Z lie in the ranges: 11.0.ltoreq.X.ltoreq.22.0; 60.0.ltoreq.Y.ltoreq.75.0; and 6.0.ltoreq.Z.ltoreq.28.0 (X+Y+Z=100) expressed in mole %, and 0
