Specification :

Steatite works very well in cold switching applications.
Steatite is used to support heating elements in electric heaters, toasters, and ovens.

Steatite is good high voltage insulator. It holds up under thousands of volts without breaking down.

Steatite ceramic parts are usually small and are formed from dry powder in a compaction press.
The parts are then fired in the kiln. Diamond abrasives are used to grind parts to size for high tolerance applications.
