We have performed bar impact experiments on aluminum oxynitride (A1ON), a transparent polycrystalline ceramic, measuring the peak stress and taking high-speed photographs. The peak stress measured in the A1ON bars is 4 GPa, about 10% higher than that measured in AD-99.5 bars. Failure was observed propagating up the center of the bar, leaving the outer part intact at relatively late times. There was anomalous damage to the witness bar, similar to what happens with glass bars, indicating either retained strength in the center column or explosive fracture of the A1ON bar.
