Abstract
The invention relates to a ceramic material for capacitors. In order to achieve reduced self-heating on assembly of the material into multilayer capacitors with antiferroelectric properties and a high dielectric constant, a ceramic material of formula ┌Pb(BaSrCa)┘(XY)A(ZrTi)Ois proposed, where X and Y both represent a rare metal earth selected from the group consisting of La, Nd, Y, Eu, Gd, Tb, Dy, Ho, Er and/or Yb; where A represents a monovalent ion; x+y+z=1; x and/or y and/or z>0; 0<r<0.3; 0<d<1; 0<a<0.2; 0<b<0.2; 0<c<0.2.
