• Piezoelectric Powder Description:

1) Piezoelectricity is the ability of certain crystals to generate a voltage in response to applied mechanical stress. The word is derived from the Greek piezein, which means to squeeze or press.

2) The piezoelectric effect is reversible in that piezoelectric crystals, when subjected to an externally applied voltage, can change shape by a small amount. The deformation, about 0.1% of the original dimension in PZT, is of the order of nanometers, but nevertheless finds useful applications such as the production and detection of sound, generation of high voltages, electronic frequency generation, microbalance, and ultrafine focusing of optical assemblies.

3) The piezoelectric effect occurs only in non conductive materials. Piezoelectric materials can be divided in 2 main groups: crystals and cermaics. The most well-known piezoelectric material is quartz (SiO2).

4) The main composition of piezoelectric ceramic powder is Lead Zirconate Titanate (PZT). The ceramic powder is made by adding a few additives in the powder materials mixed with ZrO2, PbO and TiO2, and following by a series of conscientious and careful manufacturing procedures.
