Abstract (en)
[origin: WO2022012880A1] The present invention relates to a ceramic material for a capacitor in multi-layer technology. The ceramic material has a composition according to the following general formula: Pb(y-1,5a-0,5b+c+0,5d-0,5e-f)CaaAb(Zr1-xTix)(1-c-d-e-f)EcFedNbeWfO3, where A is one or more from the group Na, K and Ag; E is one or more from the group Cu, Ni, Hf, Si and Mn; and 0 < a < 0.14, 0.05 ≤ x ≤ 0.3, 0 ≤ b ≤ 0.12, 0 < c ≤ 0.12, 0 ≤ d ≤ 0.12, 0 ≤ e ≤ 0.12, 0 ≤ f ≤ 0.12, 0.9 ≤ y ≤ 1.5 and 0.001 < b+c+d+e+f. The invention also relates to a capacitor comprising the described ceramic material.
