A piezoelectric ceramic composition comprising: a matrix material comprising at least two matrix components having a perovskite structure or consisting of said matrix components; a first matrix component being selected from (BiA)EOand BaEO; and a further matrix component being Bi(MeE)O, wherein A is selected from an alkali metal, particularly sodium or potassium, or a mixture of alkali metals; wherein E is independently selected from titanium, zirconium and mixtures of titanium and zirconium; and wherein Me is selected from bivalent metals.

Piezo-electric ceramic composition, method for producing the composition, and electric component comprising the composition

The invention relates to a ceramic material of the formula [(BiNaTiO)()(BaTiO)]() (KNaNbO), and also to a method for producing the same and to a component comprising said material.

Ceramic material, method for producing said ceramic material and component comprising said ceramic material

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&#x2212;x)(BiNaTiO)&#xd7;(KNaNbO), where 0&#x3c;x&#x2266;0.15. Furthermore, the invention relates to a component comprising said material.
