Abstract

Mechanically-blended stoichiometric powder mixtures of zinc oxide and ferric oxide have been subjected to high pressure shock wave loading between 7.5 and 27 GPa. By varying the initial packing densities between 2.15 and 3.38 Mg/m3 in recovery fixtures, peak shock temperatures between 125 and 1,100°C were achieved. X-ray diffraction shows formation of a spinel structure type. The amount depends on shock parameters; unequal consumption of initial oxides suggests a defective spinel Zn1−xFexFe2O4 rather than stoichiometric ZnFe2O4 is formed. A comparison is made between materials prepared by shock loading and by furnace firing.
