Steatite (artificial porcelain) - Used in the manufacture of insulating parts, which have greater electrical and mechanical strength than conventional porcelain materials.

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