摘　　要：利用均匀沉淀法制备得到纳米级氧化铁,研究了不同粒度的氧化铁颗粒对TNT炸药爆热的影响。结果表明:随着氧化铁颗粒度的减小,它与TNT组成的混合炸药的爆热得到有效的提高。Nanometer scale Fe_(2)O_(3 ) particles were prepared with precipitation method and mixed into TNT explosive. The effects of particle size of ultra-fine Fe_(2)O_(3) on the explosion heat of the trinitrotoluene mixture have been studied in this paper. The results show that the explosion heat of the mixture of TNT and Fe_(2)O_(3 ) increases obviously as the Fe_(2)O_(3 ) particle size reducing.
