Wollastonite Ceramic

Low Thermal Expansion Ceramic

Wollastonite is a technical ceramic used in thermal processing and refractory applications where a balance of thermal stability and cost efficiency is required.

It’s often chosen when components must:

  • Withstand high-temperature processing environments
  • Maintain stability under thermal cycling
  • Provide cost-effective refractory performance
  • Replace less stable ceramic materials
  • Support kiln and furnace operations

Important: Key advantage:

Wollastonite provides balanced thermal performance at a lower cost than many advanced ceramics.


Versatile wollastonite ceramics providing thermal stability and electrical insulation for specialized industrial applications.
