文摘
- •
A new lead-free piezoelectric system with rhombohedral–tetragonal phase boundary has been developed.
- •
The ceramics with high density have been obtained owing to their good sinterability.
- •
Good piezoelectricity (d33 = 267 pC/N, kp = 45.2%, εr = 1836, tan δ = 3.32%, Tc = 253 °C) was obtained.
