Abstract

The thick films and devices of PMN-based relaxor ferroelectric have attracted considerable attentions because they have excellent electric properties.In this paper,the research progress and trend of PMN-based thick films are summarized with emphases on screen printing,composite Sol-Gel,tape-casting,electrophoretic deposition and hydrothermal method.On the other hand,relatively slow progress was achieved in theoretical studies aimed in explaining the relaxor ferroelectric properties and the relaxor mechanism of the PMN-based thick film.Therefore,future works should involve in the low-temperature fabricating process,the physical mechanism and the new devices,which can be applied to new-type lead-free relaxor ferroelectric thick films with excellent properties.
