【Abstract】 The existing techniques and methods of nanometer aluminum oxide synthesis are briefly introduced. Experiments were carried out to study the synthesis of ultrafine aluminum oxide by the detonation of aluminum nitrate and PETN mixture. The detonation product without any disposal was analysed by TEM,XRD,DTA/TG and BET respectively.The results show that the detonation product is nanometer spherical aluminum oxide with grain size of 10 nm to 50 nm,and the average is 25nm. The poduct is γ-aluminum oxide.更多还原
