摘要： A method for manufacturing a PZT-based low-sintering piezoelectric ceramic material, the ions to be added as starting compounds being added as powdered oxides and/or powdered carbonates, mixed together, and then calcined to form the piezoelectric ceramic material. After calcining the starting compounds, lithium in ionic form is added to the mixture in an amount of 0.01 to 0.1 wt. % in relation to the weight of the PZT ceramic.

摘要： A piezoelectric ceramic material having the molar composition Pb(1+c)−x−(3/2a)−1/2(x·b)A1xA2a(Zry(1−x·b−x·z)Ti(1−y)(1−x·b−x·w))(B1bB2zB3w)xO3 where A1 is selected from the group Ca, Mg, Sr, Ba, or their mixtures, A2 is selected from the group of rare-earth elements or their mixtures, B1 is selected from the group Nb, Ta, or Sb or their mixtures, B2 is Cu or a mixture of Cu with at least one element selected from the group Zn, Ni, Co, or Fe, and B3 is Fe, and where the following applies: 0.001≦a≦0.05; 0.05≦b≦0.90; 0≦c≦0.04; 0.005≦x≦0.03; 0.5≦y≦0.55; 0.05≦z≦0.90; 0≦w≦0.5. Furthermore, an electroceramic multilayer component is described having insulating layers containing such a material. Two manufacturing methods are described for the ceramic material, metal ions being introduced as powdered oxides and/or carbonates, mixed together, and calcined to form the ceramic material, or powdered ZrO2 and TiO2 is calcined to form ZryTi1−yO2 where 0.50
