SCERAM CERAMICS is the leader of a research program sponsored by the french government (DGA). The project aims to developping big sizes transparent ceramics discs or tiles for balistic protection and dual applications,  by SPS technology (SPARK PLASMA SINTERING).
In collaboration with INSA MATEIS, and uB Filiale.

Basic properties:

- Very high mechanical resistance (wear, abrasion…)
- This ceramic represents a perfect substitute for sapphire, with lower price.    
- High temperature resistance > 1200°c.
- Perfectly dense material.
- High RIT in the visible, UV and IR (such as sapphire and quartz).
- Machinable with high precision
- Polishable
- No open porosity

Applications :

- Balistic Armor windows
- Missile domes
- Transparent watch body
