| 简介 |
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(1-r)(BaxSryCaz)r](1-1 5a-1, 5b-0, 5c)(XaYb)Ac(Zr1-dTid)O3 is 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. |
