← ScienceWhich consequence results when rapid cooling induces defects in piezoelectric crystal?
A)Reduced poling and unstable polarization✓
B)Increased dielectric breakdown strength
C)Enhanced mechanical vibration amplitudes
D)Improved thermal conductivity performance
💡 Explanation
Rapid cooling introduces dislocations which interfere with domain alignment, because the **nucleation** of domains is disrupted. Therefore, poling effectiveness decreases and the crystal's polarization becomes unstable, rather than exhibiting amplified piezoelectric effects under stress.
