Features:
Steatite is used to support heating elements in electric heaters,
toasters, and ovens.
Steatite is a 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.
