“…The DSC curves in Figure A showed both BNT and BNT–10Bi feedstock melted incongruently at 1300°C. The stoichiometric BNT is reported to be a congruent melting composition . While excess Bi 2 O 3 was added in BNT‐10Bi feedstock, BNT–10Bi feedstock did not show a congruent melting behavior.…”

“…It is known that congruent crystallization materials have the same composition in liquid phase and solid phase as crystallized . Some congruent melting compositions, such as Bi 0.5 Na 0.5 TiO 3 , LiNbO 3 , and LiTaO 3 , are reported to be suitable for single crystal growth with proper compensation of the volatile loss to realize congruent crystalliztion . BNT‐based system is also one of the most promising lead‐free piezoelectric systems due to its high remnant polarization and large electromechanical coupling coefficient .…”

Bismuth sodium titanate (BNT) piezoelectric ceramic coatings with dense morphology and single perovskite phase were fabricated by thermal spray process. The melting and crystallization behaviors of BNT near congruent composition and the effect of excess Bi composition were investigated by analyzing the heating-melting-cooling cycle for the application in thermal spray process. Crystal structure and morphology of the thermal sprayed BNT coatings were examined, and their electrical and electromechanical properties were tested. An effective piezoelectric coefficient d 33 of 50 pm/V was obtained under substrate clamping, measured with laser scanning method. The findings have shed light on the design of appropriate compositions for achieving high quality lead-free piezoelectric ceramic coatings by the scalable thermal spray process.
