Bi2O3/CNTS复合物的制备及其对双基推进剂燃烧的催化作用
Preparation of Bi2O3/CNTs Composite and Its Combustion Catalytic Effect on Double-base Propellant
摘要
Abstract
Bi2O3/CNTs composite was prepared from bismuth nitrite by liquid phase deposition method under normal temperature and normal pressure using multi-walled carbon nanotubes. The morphologies and particle size of Bi2O3/CNTs composite were determined with XRD, TEM and EDS. The catalytic effect of Bi2O3/CNTs on the combustion performance of double-base propellant was investigated. The results show that Bi2O3 is supported on CNTs equally as a ball, and the diameter of the ball is about 27nm . The Bi2O3/CNTs can enhance burning-rate of propellant by 74.7% (4MPa), and decrease the pressure exponent from 0. 7834 to 0. 4307(16-22 Mpa).关键词
