Abstract

The high ignition temperature and low combustion efficiency of boron (B) powders seriously affect the efficient application of boron-based composite energetic materials. Herein, we prepared high-energy microsphere units containing iron fluoride (FeF₃), ammonium perchlorate (AP) and B powders by using a atomization spheroidization method to improve the combustion performance and energy release efficiency of micron-B powder. The results shown that the composition of the package structure and the incorporation of FeF₃ can effectively reduce the initial oxidation and ignition temperatures of B powders by about 23.55 % and 33.2 %. Moreover, when FeF₃ content is 1 %, spherical B/FeF₃@AP composites have excellent reaction calorific value (8705.7J/g) and maximum combustion temperature (1218.9 ℃), with relative increases of 22.6 % and 39.8 %. The linear combustion rate reached 5.4 cm/s, about 157 % higher than the physical mixture B/AP. Finally, the combustion mechanism of B/FeF₃@AP was proposed by combining thermogravimetry coupled infrared spectroscopy, spectral analysis of the combustion process and combustion product analysis. This study provides valuable insights for applying boron-based composite energetic materials in the field of energetic materials

B/FeF3@AP三维高能微球：改善B粉的燃烧性能和能量释放

硼粉着火温度高、燃烧效率低，严重影响了硼基复合含能材料的高效应用。为了提高微米级B粉的燃烧性能和能量释放效率，采用雾化球化方法制备了含氟化铁（FeF3）、高氯酸铵（AP）和B粉的高能微球单元。结果表明，包层结构的组成和FeF3的掺入可有效降低B粉的初始氧化温度和着火温度，分别降低23.55% %和33.2% %。当FeF3含量为1 %时，球形B/FeF3@AP复合材料具有优异的反应热值（8705.7J/g）和最高燃烧温度（1218.9℃），相对提高22.6% %和39.8% %。线性燃烧速率达到5.4 cm/s，比物理混合B/AP提高约157 %。最后，结合热重法耦合红外光谱、燃烧过程光谱分析和燃烧产物分析，提出了B/FeF3@AP的燃烧机理。本研究为硼基复合含能材料在含能材料领域的应用提供了有价值的见解

期刊介绍： Chemical engineering enables the transformation of natural resources and energy into useful products for society. It draws on and applies natural sciences, mathematics and economics, and has developed fundamental engineering science that underpins the discipline. Chemical Engineering Science (CES) has been publishing papers on the fundamentals of chemical engineering since 1951. CES is the platform where the most significant advances in the discipline have ever since been published. Chemical Engineering Science has accompanied and sustained chemical engineering through its development into the vibrant and broad scientific discipline it is today.
