There are various materials for piezoelectric ceramics, but lead zirconate titanate, commonly abbreviated as PZT, is the most widely used material because it exhibits excellent piezoelectric properties. PZT is an inorganic compound with the chemical formula shown below. In the crystal structure, the centers of positive ions and negative ions do not match, resulting in polarization. This polarization leads to the generation of piezoelectricity. KEMET offers multi-component solid ceramics that are an improvement over traditional lead zirconate titanate ceramics. KEMET's N6 and N21 materials meet a wide range of specifications for a wide variety of applications. KEMET has been providing high quality applied products and services based on these materials for many years.
