Steatite products of the Steatit s.r.o.

Steatit ceramics are traditional and long-proven electrical insulating materials that are widely used in the electrical and engineering industries. It is a fine-grained silicate ceramic based on talc (Mg₃Si₄O₁₀(OH)₂), which has an exceptionally balanced combination of electrical, mechanical, and thermal properties.

Thanks to its high electrical strength, good mechanical resistance, and excellent dimensional stability, steatit is an ideal material for the production of precise insulating parts exposed to long-term operational loads.

Key properties of steatit ceramics

very good electrical insulation properties even at elevated temperatures
high mechanical strength in compression and bending
low thermal expansion and good dimensional stability
resistance to ageing and environmental influences
excellent machinability into complex shapes
long service life without the need for maintenance

Steatit ceramics are suitable for use in environments with a combination of electrical, thermal, and mechanical stress, where plastics and metals fail.

Typical areas of application are:

electrical engineering and power engineering
heating technology
measurement and control technology
industrial electronics
engineering applications with insulating function
