摘要: The disclosed invention relates to Bi203-ZnO-Ta205 dielectric compounds and compositions, their manufacture. of the have outstanding K, Q, TCF, TCC. Examples these properties include a K between 58 80, low loss (tan δ <0.003), TCC <30 ppm/°C. Ceramic compositions produced those represented by Bi2(ZnTa2)xO6x+3 where 0.57 ≤ x 1.0, Bi2(ZnTay)2/3O?((5y+11)/3)? 1.0 y 3.0, as well 3.0 with proviso that is not = 2.0. Solid solutions defined formula r(Bi2(Zn1/3Ta2/3)2O7)-((1-r)(Bi3/2Zn2/3)(Zn1/2Ta3/2)O7))where 0
