Abstract

Abstract: Fabricating high-quality, large-size Bi4 Ti3 O12 (BIT) ceramics is challenging; therefore, the full matrix constants of BIT ceramics have not been characterized, which notably hinders their applications. In this study, the elastic stiffness constants c 11 E and c 33 D of the BIT ceramics were determined using the ultrasonic pulse-echo method. In addition, the elastic stiffness constants c 12 E, c 13 E, c 33 E, and c 44 E were determined using resonant ultrasound spectroscopy. Furthermore, the piezoelectric stress constants e15, e31, and e33 of BIT ceramics were calculated using the formula for the relationship between different material constants.
