In order to improve the ignition ability of ignition composition and reduce its hygroscopicity , the Mg-Al alloy powder was used as the combustible agent ,potassium perchlorate (KClO4 ) was used as the oxygenant and nitrocellulose (NC) was used as the combustion performance regulator ,the Mg-Al/NC high-energy ignition powder was prepared and its performance was analyzed .The results showed that Mg-Al alloy powder and NC could greatly improve the ignition ability of ignition composition .Compared with black powder ,explosion heat of Mg-Al/NC high-energy ignition composition ,increased about 100% ,spe-cific volume increased about 30% ,and solid residue rate increased about 30% ,and the flame sensitivity , impact sensitivity ,friction sensitivity and hygroscopicity decreased .
