Abstract
The invention relates to a ceramic binary material and to a method for the production thereof. The material has piezoelectric properties and has a composition of the formula (1−x)(Bi0.5Na0.5TiO3)×(K0.5Na0.5NbO3), where 0<x≦0.15. Furthermore, the invention relates to a component comprising said material.

A ceramic material having the composition (1−x)(Bi0.5Na0.5TiO3)×(K0.5Na0.5NbO3), wherein 0<x≦0.15, wherein the ceramic material is binary.
A method for the production of a material comprising a ceramic material having the composition (1−x)(Bi0.5Na0.5TiO3)×(K0.5Na0.5NbO3), wherein 0<x≦0.15, comprising the following steps of:
- A) mixing powdery oxygen-containing compounds of Bi, Na, K, Ti and Nb in a stoichiometric ratio to produce a starting mixture,
- B) grounding and calcining the starting mixture to produce a powdery solid solution,
- C) pressing and sintering the powdery solid solution;
- wherein the ceramic material is binary.
