【Abstract】 Synthesizing nanodiamond by explosion of negative-oxigen ballance powder is a tremendous progress. Nanodiamond is drawing increasing attention of engineers because of its inherent characteristics of diamond and properties of nanomaterials. Until present,explosion is the only method for nanodiamond synthesis. In this method,TNT and RDX are the most commonly used powder. Improving the quality and decreasing the production cost of nanodiamond in order to widen its production and application is an important task for the researchers and engineers. In this paper,discussion is made on the factors that affect the yield of nanodiamond by explosion method,namely:relationship between synthesis parameters and the yield, effect of the geometry of the powder packet,the ignition powder and the cooling media.更多还原
