Definitions
- the invention relates to the modification of piezoelectric ceramic materials based on lead zirconate titanate (PZT).
- PZT lead zirconate titanate
- piezoceramic multilayer actuators based on lead zirconate titanate are largely determined by the compatibility of low-sintering PZT ceramics with the AgPd internal metallization when cofiring.
- Ag ions in PZT modifications have a high diffusivity at high temperatures (> 800 ° C) and also act as acceptor doping when installed in the PZT system.
- Acceptor substitution that is not or only partially compensated for by donor ions, such as Nb 5+ , can lead to drastic changes in the ferroelectric properties and thus also in the deformation behavior of actuator materials. This effect must be taken into account when selecting the AgPd alloy for the internal electrodes. There are limits to the reduction in the proportion of the precious metal palladium, because as the proportion of silver in the internal electrodes increases, the silver diffuses to an increasing extent into the piezoceramic.
- the deformation characteristic is achieved by anticipating the introduction of Ag + ions when sintering piezoceramic laminates with AgPd internal metallization by adding Ag when formulating the composition not stabilized by conventionally modified PZT compositions.
- the object of the invention is to prevent diffusion of Ag into the ceramic material as far as possible despite a reduced Pd content in the electrode material.
- the hypothetical complex Sr (Ag 0 , 25Nbo, 75) O 3 is used in a PZT-SAN (1-y) Pb system (Zr x Ti 1 - x ) O 3 -ySr (Ago, 25Nb 0 , 7 5) O 3 into consideration.
- composition 0.98Pb (Zr 0 , 52Tio, 4 8) O 3 -0.02Sr (Ago, 2 5Nb 0 , 75) O 3 of the PZT-SAN system with an Ag content of 0.178% by weight was compared with the model substance compared with the non-stoichiometric composition 0.98Pb (Zro, 52 Tio, 48 ) ⁇ 3 -0.02Sr (Ago, ooNbo, 75 ) ⁇ 3 without Ag + ions for acceptor-donor valence compensation.
- the properties show that it is not possible to achieve valence compensation by eliminating the acceptor deficit by diffusing Ag from the internal electrodes.
- the deformation of the non-stoichiometric composition is significantly less than that of the stoichiometric composition.
- the invention is explained in more detail using an exemplary embodiment.
- the polarization and deformation behavior of laminates without and with internal electrodes was examined.
- the interaction of the modified PZT ceramics with different AgPd alloys (AgPd 70/30 and AgPd 85/15) during the cofiring of the laminates is assessed and a solution for reducing the Pd content ⁇ 30 is shown.
- the sintering temperatures of the piezoceramics of the PZT-SAN system are in the range from 950 ° C to 1100 ° C. Examples for the compositions are 0.98Pb (Zro ⁇ 52 Tio , 48 ) ⁇ 3 -
- Fig. 1 shows the polarization behavior
- Fig. 2 shows the deformation behavior of sintered laminates made of (Zro, 52 " T ⁇ o, 4 8) O 3 - 0.02Sr (Ag 0 , 2 5Nbo, 75) ⁇ 3 ceramics without and with AgPd internal electrodes.
- the values of the coercive field strength and the deformation are for the composition of 0.98Pb (Zro, 52 ⁇ io, 48) ⁇ 3-0.02Sr (Ago, 25Nb 0
- Ag + ions to form valence-compensated compositions of the PZT system, a high level of deformation is maintained, ie the acceptor-donor effect in the system is very similar to that of the conventionally modified PZT system without internal electrodes, as also shown in FIG. 2 can be seen.
