Electronic Ceramic Components / Ceramic Electronic Parts
1. Description:
Ceramic materials are used in a wide range of applications from power distribution to smartphones.Although ceramics have traditionally been considered insulating materials, after World War II, research in material science has led to the development of new ceramic formulations that exhibit semiconducting, superconducting, piezoelectric, and magnetic properties.
Ceramic products used as electrical insulators include spark plugs, hermetic packaging, ceramic arc tubes, and protective parts (e.g., beads and tubing) for bare wires and power lines. These products are primarily used in sectors such as automotive, marine transportation, aerospace, and electricity distribution. Among these products, spark plugs represent the oldest and the most popular. They were first invented in 1860 to ignite fuel for internal combustion engines and are still being used for this purpose today. However, as the automotive industry shifts toward electric and hybrid vehicles, demand for ceramic spark plugs is expected to drop. The main suppliers of these products are directing their know-how in electroceramics toward other components such as ceramic solid-state batteries.
