Pb-free Piezoelectric Elements Description
Pb-free Piezoelectric Element refers to a piezoelectric component that is free of lead (Pb). Piezoelectric materials generate an electric charge in response to mechanical stress or deformation. It features stable piezoelectric performance in a wide temperature range due to high Curie temperature.
Barium titanate, with the chemical formula BaTiO3, is a ferroelectric ceramic material that exhibits interesting and useful properties. It undergoes a phase transition at a certain temperature (Curie temperature) where it becomes ferroelectric, meaning it can exhibit spontaneous polarization. This property makes it valuable in applications like capacitors and non-volatile memory devices.
