| 摘 要： | 以没食子酸、硝酸铋和硝酸氧锆为原料, 首次合成出了双金属有机盐——没食子酸铋锆, 采用有机元素分析、X射线荧光(XRF)光谱和傅里叶变换红外(FTIR)光谱对其进行了表征. 在程序升温条件下, 利用热重(TG)分析、差示扫描量热法(DSC)、固相原位反应池/FTIR 联用技术, 研究了没食子酸铋锆的热行为和热分解机理,描述了没食子酸铋锆的热分解过程, 分析得出其最终分解产物为Bi2O3、ZrO2和C. 利用螺压工艺制备了含没食子酸铋锆的推进剂样品, 研究了没食子酸铋锆对双基(DB)推进剂燃烧性能的影响, 分析了其燃烧催化作用. 结果表明, 没食子酸铋锆对双基推进剂的燃烧具有良好的催化作用, 是一种高效的燃烧催化剂; 没食子酸铋锆热分解的最终产物是催化燃烧的主要物质, 锆和碳则起辅助催化的作用.

| Abstract: | Bismuth/zirconium gallate (Gal-BiZr) was synthesized from gallic acid, bismuth nitrate, and zirconyl nitrate firstly, and characterized by elemental analysis, X-ray fluorescence (XRF), and Fourier transform infrared (FTIR) spectroscopies. The thermal behavior and decomposition mechanism of Gal-BiZr in a temperature-programmed mode were investigated by thermogravimetric (TG) analysis, differential scanning colorimetry (DSC), and condensed phase thermolysis/FTIR techniques. The decomposition products of Gal-BiZr are Bi2O3, ZrO2, and C. Samples of propellants containing Gal-BiZr were prepared by extrusion technology, and the effect of Gal-BiZr on double-base (DB) propellant combustion properties was investigated. Gal-BiZr exhibits good catalytic behavior in the combustion of DB and Hexogeon (RDX)- CMDB propellants. |
