Thermal Effects

1) A pyroelectric charge is generated by most piezoelectric ceramic when subjected to a temperature change.
The magnitude of this charge in lead zirconate titanates is about 2 x 10^-4 coulombs/m²  °C.

2) Thermal expansion coefficient (in parts/million/°C).

3) Heat capacity of C5400 and C5500 approximately 420 joules/kg °C.

4) Thermal conductivity C5400 and C5500 approximately 1.8 watts/meter °C.
