Pechiney developed Geopolymer refractory materials for safe casting of corrosive aluminum/lithium (Al/Li) alloys in liquid state. Source: Pechiney patent
Since 1986, the French aeronautic company Dassault Aviation is using geopolymer mold and tooling in the development of the Rafale fighter plane.

In addition, we made for Northtrop Aviation a geopolymer composite tooling prototype (self-heated carbon/SiC/Geopolymite composite) used in the fabrication of carbon/APC2 composite designed for a new US Airforce bomber.
More than a hundred tooling and items has been delivered for aeronautic applications (Airbus) and SPF Aluminum processing. Sources: various annual reports, patents, technical papers.
In the recently updated book Geopolymer Chemistry & Applications these applications are outlined in Chapter 20. You may also go to the Geopolymer Library and download several papers.
