Abstract:
Explosive synthesis of ultradisperse aluminum oxide in an oxygen-containing medium is studied. Synthesis conditions that are most optimal for production of the material in the ultradisperse state are determined. A physical model of the process is proposed. It is shown that attenuation of the shock wave causes separation of the shock-compressed material into liquid and solid layers. Possible mechanisms of aluminum combustion with subsequent dispersion of aluminum into the oxygen-containing medium of the explosive chamber are considered. It is shown that ultradisperse aluminum oxide powder is produced mainly from the second layer of the shock-compressed material. Experimental dependences of the yield of the disperse fraction on synthesis conditions are explained using the model proposed.
