Abstract
The results of an x-ray diffraction investigation of iron aluminate with unit cell parameter a = 8.090(4) Å, cation-defective iron aluminate Fe0.5Al2.23O4 with a = 8.002 Å, and a new modification of aluminum oxide synthesized under shock waves from explosives containing aluminum are presented. Aluminum oxide can crystallize in the hexagonal system in a primitive lattice with a = 9.151(1) Å, c = 7.945(2) Å, V = 576 Å3 or in a tetragonal system in a primitive lattice with one-half the volume — a = 7.941(2) Å, c = 4.575(1) Å, V = 288 Å3.
