Further, lead oxide powder is spread on the edge of the inner crucible, so that the content of lead is fully ensured. In addition, on the basis of stacking a PZT ceramic blank and presintered powder by a traditional solid-phase sintering method, PZT gaskets of an upper layer and a lower layer are added, and the temperature difference in the sintering process is optimized, so that the high-temperature sintering is more uniform and stable.

Description
Technical Field
The application relates to the technical field of ceramic sintering, in particular to an optimization method of a PZT-based piezoelectric ceramic solid-phase sintering process.
Background
The piezoelectric ceramic is an important functional material capable of realizing the mutual conversion of electric energy and mechanical energy, has low cost and good adjustability, and is widely applied to various fields of daily life. In the preparation process of the piezoelectric ceramic, powder preparation, compression molding and high-temperature sintering are three important processes. The high-temperature sintering is a key link for preparing ceramics, and the design choice of the sintering process directly influences the mechanical properties such as grain size, density, porosity and the like of the ceramics, and the dielectric and piezoelectric properties.
The piezoelectric ceramic sintering process mainly comprises a plurality of methods such as normal pressure solid phase sintering, hot pressing sintering, hot isostatic pressing sintering, microwave sintering, spark plasma sintering and the like. The normal pressure solid phase sintering is the most widely applied technology in the preparation of PZT-based piezoelectric ceramics due to the characteristics of low cost and good stability. In the conventional solid-phase sintering process design, the sintering temperature of PZT-based piezoelectric ceramics is usually set to about 1100-1300 ℃, and the main components in the ceramic raw materials, pb oxide PbO and Pb 3 O 4 Can volatilize in a large amount at a lower temperature of 900-1000 ℃, so that the problems of component segregation and the like of a final sample are caused, and even a second phase is formed, so that the movement of a crystal boundary and a domain wall is limited, and the related mechanical and piezoelectric properties of the ceramic are seriously affected.
In the traditional solid-phase sintering method of PZT-based piezoelectric ceramics, a certain amount of lead oxide raw material is usually added in the powder preparation stage to avoid massive volatilization of lead at high temperature, but the addition of excessive lead oxide cannot effectively inhibit volatilization of lead. Excessive lead oxide liquid phase can also inhibit grain boundary movement and material diffusion, so that the problem of density reduction of ceramic products occurs. The method has the advantages that the traditional solid-phase sintering method is optimally designed, a new process for improving the performance and the manufacturing stability of the PZT-based piezoelectric ceramic is sought, lead volatilization in the sintering process is reduced, the uniformity of ceramic components is improved, and the method has important significance for mass production and performance stability improvement of the PZT-based piezoelectric ceramic.
Disclosure of Invention
The application aims to provide an optimization method of a PZT-based piezoelectric ceramic solid-phase sintering process, which solves the problem that the performance of ceramic products is easily affected due to the fact that a large amount of lead volatilizes in the PZT-based piezoelectric ceramic solid-phase sintering process.
In order to achieve the above purpose, the application provides an optimization method of a PZT-based piezoelectric ceramic solid phase sintering process, which specifically comprises the following steps:
step one, adding excessive Pb when preparing PZT-based piezoelectric ceramic pre-sintering powder before high-temperature sintering 3 O 4 The powder is used to increase the densification rate during sintering.
Specifically, excess Pb 3 O 4 The proportion of the powder is 1-3%.
Specifically, excess Pb 3 O 4 The proportion of the powder was 1%.
And secondly, placing the PZT blank body in a crucible with a smaller model in a mode of stacking the PZT blank body up and down, and separating the PZT blank body by presintered powder with corresponding components.
Specifically, the PZT ceramic plates with corresponding components are used for replacing pre-sintered powder on the uppermost and the lowermost plates, so that the temperature difference of the intermediate green body in the sintering process is reduced.
Specifically, the stacking number of PZT embryo bodies is 3-5.
In particular, the uppermost and lowermost ceramic sheets are reusable.
Step three, spreading a proper amount of Pb around the blank inside the smaller-sized crucible used in the step two 3 O 4 Powder to provide sufficient lead element compensation during sintering.
And step three, nesting a larger-type crucible with opposite placement directions outside the smaller-type small crucible used in the step two.
Specifically, the larger size crucible in step three should be able to completely cover the crucible used in step two.
Compared with the prior art, the application has the beneficial effects that:
according to the optimization method of the PZT-based piezoelectric ceramic solid-phase sintering process, disclosed by the application, a sintering atmosphere with high lead partial pressure is formed, so that a great deal of volatilization of lead in the traditional solid-phase sintering process is inhibited, the process method is easy to realize, the practicability is high, and the properties of uniformity, compactness and the like of components of ceramic products in the traditional solid-phase sintering process can be effectively improved.
In the solid phase sintering process, a proper amount of Pb in the presintered powder 3 O 4 The powder can form liquid phase in the early and middle stages of sintering to increase the densification rate of PZT-based piezoelectric ceramics. Diffusion coefficients of main elements Pb, zr and Ti in PZT-based piezoelectric ceramics are different, and PbTiO 3 Will preferentially generate PbZrO 3 Can be synthesized at higher temperature, and lead volatilization can lead to PbZrO 3 The synthesis of (3) is not satisfactory to expect, zr precipitation is formed, grain boundary migration and substance diffusion are blocked, and the density of the ceramic is reduced. Inside and outside crucible and Pb with proper allowance 3 O 4 Under the combined action of the powder, a high-temperature sintering atmosphere with high lead partial pressure is formed, the volatilization of excessive lead in the sintering process is inhibited, and meanwhile, the environment is protected. The volatilization of lead is relieved, so that PbZrO during the synthesis process of the PZT-based piezoelectric ceramic 3 The synthesis of the ceramic is smoother, the second phase precipitation at the grain boundary is avoided, and the density and the component uniformity of the ceramic are improved.
The process optimization process only adds a crucible nested structure with lower cost and a small amount of pre-sintered powder to spread, so that the cost of the process optimization is not obviously improved and the process difficulty is lower while the expected ceramic performance requirement is met.
A double-layer nested structure is designed in the sintering process of the PZT-based piezoelectric ceramic to form a high-lead partial pressure sintering atmosphere, so that excessive volatilization of lead is reduced, and the generation of a second phase in the sintering process is avoided to influence the mechanical and piezoelectric properties of the ceramic. The setting of the high lead partial pressure sintering atmosphere is simple, the preparation cost is low, and the effect is obvious.
