摘要
用 Pb(NO3 ) 2 、Bi(NO3 ) 3 和 Na OH为原料 ,通过室温固相反应 ,制备出纳米 Pb O和纳米 Bi2 O3 粉末 ,用 X-射线衍射仪和透射电镜对产物的组成、大小和形貌进行了表征。用纳米 Pb O和 Bi2 O3 作燃速催化剂 ,在 RDX- CMDB推进剂中进行了配方试验研究。实验结果表明 ,纳米 Bi2 O3 能够提高推进剂的燃速 ,同时降低压强指数。
Nanometer PbO and Nanometer Bi 2O 3 were synthesized by solid state reaction using Pb(NO 3) 2, Bi(NO 3) 3 with NaOH at room temperature. The crystal form, particle size and morphology of nanometer PbO and Bi 2O 3 were characterized by XRD and TEM. The effect of two nanometer catalysts on burning Properties of RDX CMDB propellant were investigated. The results show that nanometer Bi 2O 3 can increase the burning rates of the propellant and lower burning rate pressure exponent.
