Abstract :
Bismuth tungstate, Bi2WO6(BWO), mono-domain crystals grown by a slow cooling technique were characterized. Observation of the etch-pit patterns of all the crystal substrate surfaces confirmed that the grown crystals consisted of a mono-domain fabric. The electromechanical coupling factor, k31, and mechanical quality factor, Qm, of the crystals were 24% and over 4000 at room temperature, respectively. The resonance response revealed that the BWO crystals maintained the piezoelectricity up to 400degC.
