Silicates

Family Overview

Silicate ceramics, the oldest family of ceramics, are multi-phase materials developed from natural silicate sources such as clay, kaolin, feldspar, and soapstone. Today’s silicates — including cordierite, forsterite, mullite, steatite, and technical porcelain — evolved from traditional ceramics and are useful for cost-effective technical applications such as electrical insulators and chemical labware.

Cordierite

Cordierite is a cost-effective material suitable for mass production and is available in both dense and open porous forms. The material exhibits strong electrochemical and chemical resistance, along with good arc resistance. It offers high thermal shock resistance and low heat capacity. Its homogeneous structure supports efficient heat dissipation.

Example Applications:

  • Perforated Plaques and Infrared radiators 
  • Spark arresters
  • High current applications
     

Contact a CoorsTek expert to choose a Cordierite solution for your application.

Forsterite

Forsterite is used in electronics, often as silicate substrates, because of its good electrical and dielectric properties. 

Example Applications:

  • Sensors
  • Electrical substrates

Contact a CoorsTek expert to choose a Forsterite solution for your application.

Mullite

Mullite has excellent thermal shock resistance and dielectric strength, making it ideal for electronic components for manufacturing purposes.

Example Applications:

  • Ceramic tubes
  • Metal foundry filters

Contact a CoorsTek expert to choose a mullite solution for your application.

Porcelain 

As the company's longest running line of technical ceramics, CoorsTek chemical and scientific labware has become an industry standard. After glazing, CoorsTek porcelain labware resists corrosion and demonstrates superior thermal properties. Search the CoorsTek Labware Store to find the right piece of equipment for you. 

Example Applications:

  • Chemical & scientific labware
  • Electrical insulators

Contact a CoorsTek expert to choose a porcelain solution for your application.

 

Steatite

Steatite is a cost-effective material engineered for high-temperature environments and long-term stability. Its resistance to ageing and suitability for mass production make it ideal for industrial use. Steatite performs well in high-frequency applications and offers reliable wear and chemical resistance, while maintaining dimensional stability under heat.

Example Applications:
