<p>A mineral insulated electrical component, such as a cable (18) or sensor is provided with a ceramic insulator formed primarily from aluminum nitride. The aluminum nitride insulator is constructed from a ceramic preform (10) or sintered, granulated powder composed of up to 99 % aluminum nitride, with the remaining portion being selected from a group of sintering aids, including yttrium oxide. The addition of yttrium oxide allows the aluminum nitride to be fired into a stabilized, swageable ceramic, or further into granulated, stabilized powder. The ceramic allows the fabrication of aluminum nitride-yttrium oxide insulated heater cables, insulated thermocouples, insulated electrical cables, or the like.</p> |
