Ceramic Electrical Conductivity Guide: Al2O3, AlN, SiC and ESD-Safe Ceramics

Ceramics are often described as electrical insulators, but this description is incomplete. In semiconductor equipment, electronics manufacturing, vacuum systems, wafer handling, and precision automation, ceramic components may be required to perform very different electrical functions. Some components must provide extremely high electrical insulation. Others need controlled semiconductive behavior to prevent static charge accumulation. Certain silicon […]
