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.

Key words: PMN, relaxor, ferroelectric, thick film, review
