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. A composition of a first component and a composition of a second component has respective permittivities TKεAand TKεB. In the ceramic material, temperature components of the permittivities TKεAand TKεBhave different signs within a temperature interval.
