Synthetic Cordierite

Synthetic Cordierite

Final Advanced Materials provides a range of pressed technical ceramic. Pressed technical ceramics are mainly used to produce parts in big quantities for application where there is no need for tight dimensional tolerances, chemical purity or high mechanical stress for example. This type of ceramic is more economical than sintered ceramics like alumina or zirconia. We can mould ceramic parts according to your needs for applications over 1000°C.
