Steatite Ceramic Parts
Talc based insulators for heating elements sockets and transformers
The 3 Products in This Family
Steatite is made from natural mineral talc, 3MgO 4SiO2 H2O, with clay and BaTiO3 additions. It is the standard body for electrical insulation because the volume resistivity holds up at elevated temperature and the dielectric loss stays low. Parts run from single beads up to strips, channels, bricks, knuckles, tiles and blocks with a working temperature of 1100 degrees.

Steatite Ceramic PartsIndustrial Ceramic Insulator Heating Ring Ceramic StripOne to eight hole strips for flexible ceramic pad heatersView specificationsProblems This Family Solves
- Insulators losing resistivity as soon as the assembly reaches working temperature
- Rigid insulating tubes that cannot follow a coiled or bent heating element
- Sourcing several different insulator shapes from several different suppliers
Core Advantages
- High volume resistivity retained at elevated temperature
- Low dielectric loss factor so the insulator does not heat itself
- Seven form families cover most heater socket and terminal geometries
- Good thermal conductivity, so the insulator does not block the heat path

Steatite Ceramic Parts FAQ
What temperature can steatite run at?
The working temperature of these steatite insulators is 1100 degrees.
What is steatite made from?
Mineral talc, 3MgO 4SiO2 H2O, as the main raw material, with appropriate amounts of clay and BaTiO3, mixed, ground, formed and sintered at high temperature.
Can you supply fish spine insulators?
Yes. Bush, bead and fish spine forms are standard, and custom shapes are made from drawing.
When should I move from steatite to alumina?
Above the steatite service range, or where the part also has to resist abrasion.
