Natural Cordierit

Overview: Natural Cordierite

Natural cordierite is a natural ceramic which is sourced from a pyrophyllite rock. Final Advanced Materials employs a mineral which is endowed with exceptional mechanical and thermal performance capabilities. After high-temperature treatment, this material acquires properties which are similar to those of known synthetic ceramics.

The remarkable flexibility of application of natural cordierite permits the resolution of issues raised by ceramics in laboratories and design offices.

Natural cordierite is frequently a key element of projects, because of its properties:

Dielectric and thermal insulating capabilities
Resistance to thermal impacts
Resistance to abrasion
Resistance to chemical agents
Dimensional stability and accuracy
Suitability for metal plating
Heat-resistant up to 1,300 °C
Non-combustible
Low absorption of humidity
Excellent under high-pressure vacuum (up to 10-8 torr)
Limited production time
Fusion compatibility with aluminium, zinc, lead, sodium or cast iron
Absence of glass marking
Compliance with food grade testing in accordance with NF EN ISO standard 10545-15

Natural cordierite shows very low shrinkage (≤ 1 %), and remains stable at high temperatures. It can be used at temperatures up to 1,300 °C, provided that a specific thermal treatment procedure is observed.

Product Range in Natural Cordierite

Machinable Natural Cordierite Ceramic

Machinable natural cordierite ceramic provides a highly cost-effective alternative to sintered ceramics for applications at temperatures up to 1,300 °C. Thereafter, thermal withstand is achieved by heat treatment at 940 °C, 1,100 °C or 1,300 °C. Where tolerances are highly restricted, finishing with a diamond wheel may be necessary.</p>

Natural cordierite also provides a useful alternative to Macor^®, depending upon the dimensions and the machining tolerances of the part to be produced.

Final Advanced Materials can supply ceramic rods or plates for your own use, but it is also possible for us to undertake the complete execution of your project.
