Introduction to Thermiculite ® SOFC

Thermiculite® 866 is a sealing material specifically designed as a compression seal for Solid Oxide Fuel Cells (SOFC). It is proving to be very successful in a range of SOFC applications around the world.Thermiculite® 866 is a product utilising the Thermiculite® technology, based upon the use of chemically exfoliated vermiculite, that has been developed by Flexitallic to produce a range of high temperature, patented, sealing materials for industrial sealing.Vermiculite, a naturally occuring mineral closely related to mica, a mineral noted for high temperature capability, high chemical resistance, and an electrical insulator. Both mica and vermiculite occur naturally as flakes which consist of a stack of very many crystal plates where each crystal plate is nanometres thick. Those flakes of vermiculite, unlike those of mica, are able to be exfoliated so that the crystal plates seperate from each other.
