摘要: The relation between the parameters of mixed explosives [combinations of Al(NO3)(3)center dot 9H(2)O powder, RDX powder, and/or polyethylene foaming particles] and the phase and dimension of ultrafine Al2O3 is studied in this paper. Experimental results indicate that mixed explosives with a high density of 1.8 g/cm(3) are adapted to prepare high-temperature alpha-Al2O3. Ultrafine (alpha + gamma)-Al2O3 with alpha-phase dominance is synthesized by the detonation of charges with a medium-high density of 1.3 g/cm(3). Explosives with a medium-low density of 0.8 g/cm(3) synthesize low-temperature pure lambda-Al2O3.
