Lead-free piezoelectric ceramics based on bismuth sodium titanate (BNT) -barium hafnate titanate (BHT) were prepared by a two-step synthesis process. The final BNT-BHT ceramics sintered at 1180oC for 2 h in air showed a perovskite structure with high density. The morphotropic phase boundaries (MPB) were found in BNT based piezoelectric ceramics with 8~10 wt% BHT in composites. In the case of Bi0.5Na0.5TiO3-0.08BaHf0.05Ti0.95O3 ceramics, a maximum piezoelectric coefficient d33 of 122.6 pC/N was obtained. The remnant polarization (Pr) and coercive field (Ec) were measured and the relationship between ferroelectricity and the BHT fraction in the compounds was investigated. The BNT-BHT ceramics were expected to be a new and promising candidate for lead-free piezoelectric device applications.

There are a large number of research publications on the hot topic of environmental friendly lead-free piezoelectric materials worldwide in the last decade. The number of researchers and institutions involved from China is much larger than other countries or regions. The publications by Chinese researchers cover a broad spectrum on the preparations, structures, properties and applications of lead-free piezoelectric ceramics. This has motivated us to come out with a review on recent advances in development of lead-free piezoelectric ceramics in China. The emphases are especially on the preparation and electric properties of barium titanate-based materials, bismuth sodium titanate and related materials, alkaline niobate and related materials, bismuth layer-structured materials, as well as texture engineering of ceramics and some of their single crystals. Hopefully, this could give further impetus to the researchers to continue their efforts in this promising area and also draw the attentions from legislature, research office, industrial and publics.
