Which term describes the loss of piezoelectric properties due to heat exposure?

Which term describes the loss of piezoelectric properties due to heat exposure?

• A. Destroyed
• B. Preserved
• C. Recovered
• D. Stabilized

Answer: (A)

Heat can irreversibly disrupt the alignment of domains in a piezoelectric material and may drive it past its Curie temperature, causing depolarization. When the polarization is lost or the crystal structure is damaged beyond recoverable reorientation, the material no longer exhibits piezoelectric behavior. That irreversible loss is best described as destroyed. The other terms imply the property is still present, recoverable, or stabilized, which doesn’t fit a heat-induced, permanent degradation.
