文摘
- •
The full set of material constants of 6BZ/2BLT/92NKN ceramics was obtained.
- •
Values of d33 and d15 of 6BZ/2BLT/92NKN ceramics were 321 and 602 pC/N, respectively.
- •
The piezoelectric properties of 6BZ/2BLT/92NKN ceramics are relatively stable against temperature up to 200 °C.
- •
The main origin of the enhanced piezoelectricity of 6BZ/2BLT/92NKN is the weakened polarization anisotropy.
