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.

@@@@Bismuth/zirconium gal ate (Gal-BiZr) was synthesized from gal ic 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 propel ants containing Gal-BiZr were prepared by extrusion technology, and the effect of Gal-BiZr on double-base (DB) propel ant combustion properties was investigated. Gal-BiZr exhibits good catalytic behavior in the combustion of DB and Hexogeon (RDX)-CMDB propel ants.
