Abstract
This article mainly combines the high-energy ball milling and wet solvent purification method , using nano scale powder by ball milling treatment on boron powder to prepar of composite material.The paper discuss the effects of different boron magnesium ratios on the combustion properties of boron powder.First, in accordance with boron and magnesium (6:1,8:1,10:1) ratio weighed three metal powders, which were added to the ball mill jar, n-hexane as a solvent, ball handling centrifugal drying three hours later, obtained boron - magnesium composite material.Then, the above three samples were characterized TG-DSC thermal analysis, and boron and boron to make a simple comparison of the milling process, in order to analyze the thermal performance.Finally, the samples were formulated in three different proportions B/BaCrO4 extended drug tested and compared the activity of combustion.
In summary, when preparing boron - magnesium composite material, boron and magnesium ratio of 10:1 works best when the oxidation weight gain increased 13.44% than as boron powder, put the heat to improve 31.92%, fuel ratio of pure boron powder postponed burning rate of the drug improved 99.36%.

1 绪论
单质硼为黑色或深棕色粉末(如图1.1)，在空气中氧化时由于三氧化二硼膜的形成而阻碍内部硼继续氧化。常温时能与氟反应，不受盐酸和氢氟酸水溶液的腐蚀。硼不溶于水，粉末状的硼能溶于沸硝酸和硫酸，以及大多数熔融的金属如铜、铁、锰、铝和钙。硼在常温时为弱电导体，硼的熔点为2076℃，沸点为3927℃，而在高温时导电良好[1]。
