Powder compacts of magnetite and zirconia have been subjected to controlled, quantitative high pressure shock loading at peak pressures from 5-27 GPa. X-ray diffraction lines are broadened, indicating considerable reduction of the crystallite size and introduction of residual microstrain. At higher pressures, different shock-induced reactions are observed in these two materials. 10 refs., 2 figs., 2 tabs.
