Ballistic Behavior of New Alumina Composites Reinforced with Niobo-Phosphate Glass

This work aimed to produce and evaluate the ballistic behavior of niobo-phosphate glass-doped alumina composites. The niobo-phosphate glass (30% Nb2O5- 30% P2O5- 20% CaO - 20% CaF2, by mol) were added to the alumina in six different weight percentages. The composite with the highest densification, measured by the Archimedes assay, was used for the ballistic tests. X-ray diffraction (XRD), scanning electron microscopy (SEM) and X-ray spectroscopy by dispersive energy (EDX) were also performed. The sintered samples were enveloped on two 1020 steel plates for the residual velocity test. The best ...
