【Abstract】 Based on the low temperature combustion sythesis of α Al 2O 3 from aluminium nitrate,the effects of the additive and ignited methods on the formation and particle properties of α Al 2O 3 were studied by XRD and SEM,the initial study on the nanometer α Al 2O 3 sythesis by LCS was made,α Al 2O 3with the particle size 60～80 nm was got under proper conditions.The sintering characters of the α Al 2O 3 synthesized by different processes were studied preliminaryly.更多还原
