摘要： The invention relates to a piezoelectrical bending converter (1) with at least one monolithic layered composite (2, 21), comprising a piezoelectric-active ceramic layer (31) with a lateral dimension change (311) which may be generated by application of an electrical field (312) and at least one further piezoelectric-active ceramic layer (32) with a further lateral dimension change (321), different from the lateral dimension change (311). The bending converter is characterised in that an electrode layer (411) is arranged between the ceramic layers, for generation of the electric fields. The layered composite preferably comprises several piezoelectric-active layers and electrode layers arranged between the above. The shift is thus obtained as a gradient of the dimension changes in the direction of the stack (22) of the layered composite. The dimension changes for the ceramic layers and thus the gradient may be adjusted by means of the generation of the electrical fields. In order to achieve a shift it is necessary not to have a piezoelectric-inactive layer. The layered composite is preferably a circular disc bending body (21), with a circular base body. A large shift ratio is obtained by means of arranging several circular disc bending bodies in a stack.

摘要： The invention relates to a method for producing a lead-free piezoceramic material, comprising at least one perovskite phase of the potassium-sodium-niobate system (PSN). The perovskite phase comprising the composition (K0,5Nb0,5)O3 is produced by means of the following method steps: a) preparation of a mixture of starting materials of the perovskite phase, and b) heat treatment of the mixture. The method is characterised in that a powder comprising niobium hydroxide (Nb(OH)3) is used as one of the starting materials. The heat treatment consists of calcination and/or sintering. The use of the highly reactive niobium hydroxide as a starting material (precursor) simplifies the formation of a PSN ceramic free from phase shift, during the calcination. The method enables a piezoceramic component in the form of an ultrasound converter or a piezoceramic bending transducer to be produced. The accessible piezoceramic component is especially a multilayer piezoelectric actuator which is used to control a fuel valve of an internal combustion engine of a motor vehicle.
