High dielectric strength and high volume resistivity, coupled with good thermal dissipation, make alumina the material of choice throughout electrical engineering. For feed-through insulators, housings, high-performance semiconductors, silicon-controlled rectifier, surge arresters and vacuum interrupters. A wide range of metallization are available with Mo-Mn, W, AG, Tin, Ni, Tin and AU, etc. Glazing can be optionally applied.
