NIOBOPHOSPHATE GLASSES FOR BALLISTIC APPLICATIONS

The potential of a niobophosphate glass was investigated with respect to the ability to act as a ceramic shield for multi-layer shields. The glass was designed to have the following molar composition: 30% Nb2O5– 30% P2O5– 20% CaO – 20% CaF2. Glass, heat treated glass (glass ceramic) and alumina-reinforced with glass samples were used as the ceramic component for multi-layer shields.
Ballistic tests were performed in order to assess the residual velocity of the projectile. The results from the residual velocity tests indicated higher energy absorption for the glass-reinforced alumina samples, in comparison to pure alumina, indicating a promise use of this glass for ballistic applications.
