Superpyrostat

Superpyrostat is used soft-fired. The porous high-frequency steatite is convincing because of its good machinability. The material is fired at temperatures between 800° and 1,100° C. Superpyrostat consists basically of soapstone, clays and fluxing agents.

Significant strengths of this material in accordance with DIN VDE 0335/DIN EN 60 672:

  • Strength and porosity can be specifically adjusted
  • High volume resistivity
  • High machinability
  • Low shrinkage, allowing good dimensional stability
  • Complex components easy to manufacture
  • Made from very economical raw materials, guaranteeing a good price-to-performance ratio

Modern examples of customized products:

  • High-performance cartridges
  • Seals in lambda probes
