Abstract: A ceramic mixed system is proposed that includes a two-phase mixture of pure components A and B, wherein phase A is based on the cubic to tetragonal modification of Bi3NbO7 and phase B is based on a monoclinic pyrochlore modification of Bi2(Zn2/3Nb4/3)O7. The electrical properties of ceramics produced therefrom make the material suitable for components having a multilayer structure in which capacitors and inductors are integrated and which can be used in data processing or signal processing.

Abstract: A capacitor includes at least two pairs of opposing electrode layers and an intermediate dielectric layer. The intermediate dielectric layer includes a ceramic material that contains at least two different components existing in separate phases. The at least two different components have a perovskite structure that contains silver in A-positions and niobium and tantalum in B-positions. A composition of a first component and a composition of a second component are such that temperature coefficients of respective permittivities Tk?A and Tk?B have different signs within a temperature range.

Abstract: A ceramic material includes at least two different components. Each of the components is present in separate phases. Each of the components has a perovskite structure which contains silver in A positions and niobium or tantalum in B positions.

Abstract: A method of producing a ceramic object includes producing particles of a type A and a type B. Each particle has a dimension of at least 5 ?m and each type of particle includes a ceramic material that is based on a mixture of silver oxide, niobium oxide and tantalum oxide. The method includes producing a particle mixture by mixing the types of particles, producing a green compact by compressing the particle mixture, and sintering the green compact.

Abstract: The invention relates to a ceramic material that contains at least two different components, each of which is present in phases separate from one another, in which each of the components exhibits a perovskite structure, which contains silver in the A positions and niobium and tantalum in the B positions, and in which the composition of a component A and the composition of a component B is each selected in such a way that the temperature coefficients of their relative permittivities TK&egr;A and TK&egr;B exhibit different signs within a temperature interval. The mixing ratio of component A to component B is advantageously selected in such a way as to produce, in keeping with the Lichtenecker rule, the most complete compensation possible of the temperature dependency of the temperature coefficients of the relative permittivities TK&egr;A and TK&egr;B.
