The alumina nano-powders were prepared by combustion method.Aluminum isopropoxide mixed with isopropanol and diethylene glycol monobutyl ether（DGBE） in certain proportion were injected into furnace by the self-designed burner with O_2,liquid gas and air at rates of 8kg/h.It gave nano-alumina,whose particle size was blew to 60 nm,specific surface area was about 57m~2/g and average pore diameter was llnm.The alumina nano-powders consisted several crystal phase structure.
