Synthesis of the new modification of alumina, gahnite, and zincite upon detonation

The results of a study of the explosion products of charges of aluminum with HMX, surrounded by a brass sheath, under conditions of complete afterburning in air are presented. The condensed explosion products contain ganite ZnAl ₂ O ₄ , a new (metastable) modification of aluminum oxide and zinc oxide in small amounts. The X-ray diffraction pattern of aluminum oxide is indexed in a cubic face-centered lattice with the parameters: a = 7.854 (1) A, V = 484.4 (2) A ³ . Possible Fedorov groups are Fm3m, F432 and F43m.
