AI Customer ServiceCeramic capacitors also use rare earth elements. Pretty much any piece of modern electronic equipment will contain ceramic capacitors. Semiconductors (transistors, diodes, and the integrated circuits built from them) all use various amounts of rare earth elements. Pure silicon is a semiconductor by itself, but it doesn't do much of interest.

Supercapacitors (SCs), also known aselectrochemical capacitors, are widely studied for their high power density, fast charge and discharge and long cycle life. Rare earth is a group of elements with unique structure and properties.
Ceramic capacitors are an indispensable component in electronic circuits, since they are used in various applications such as timing, filtering, and decoupling. These capacitors are doped with REEs that improve their operating life and electrical properties.
All these capacitors are doped with REEs of intermediate ionic radii (such as Dy, Ho, and Er), since they improve the operating life (reliability) and electrical properties of the ceramic capacitors. The improvements in electric properties are a lower dissipation factor, lower aging rate, and a stable capacitance over a wide temperature range.
The advantages of REE dopants in ceramic capacitors make REEs some of the most critical elements in the electronics industry. Given the shortages in the supply of REEs, the prices of REEs will climb significantly.
