| 摘 要： | 用Pd(NO3)2、Bi(NO3)3和NaOH为原料，通过室温固相反应，制备出纳米PbO和纳米Bi2O3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PbO和Bi2O3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Bi2O3能够提高推进剂的燃速，同时降低压强指数。

| Abstract: | Nanometer PbO and Nanometer Bi2O3 were synthesized by solid state reaction using Pb(NO3)2, Bi(NO3)3 with NaOH at room temperature. The crystal form, particle size and morphology of nanometer PbO and Bi2O3 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 Bi2O3 can increase the burning rates of the propellant and lower burning rate pressure exponent. |
