Steatite (artificial porcelain) - used in the production of insulating parts with higher electrical and mechanical strength than conventional porcelain materials.

Advantages over ceramics:
- Greater mechanical strength,
- higher dimensional stability,
- higher temperature resistance (1000 0C and above).
- higher resistance to acids,
- longer service life,
- it has an insulating surface and the surface electrical leakage is zero, this material is more efficient.
