JDKNN
Lead Free Piezoelectric Ceramic Material
Our KNN series of lead-free piezoelectric ceramic materials have high piezoelectric and dielectric constants, with a d33 of 350, a dielectric constant of 2200 and a high Curie temperature of 230°C. They are the first choice for replacing lead-based piezoelectric ceramic materials.
Material parameter:
| Type | Unit | JDKNN |
| Piezoelectric changing constant | d33（PC/N） | 350 |
| Dielectric constant | εr | 2200 |
| Electric coupling constant | Kp | 0.50 |
| Mechanicalquality constant | Qm | 70 |
| Dielectric loss | Tgδ（%） | 3 |
| Curie temperature | Tc（℃） | 230 |
| Sintering temperature | ℃ | 1140 |
