金属氧化物及金属氟化物改性硼粉的燃烧性能研究进展OA

To address the challenges of difficult ignition,low combustion efficiency,and incomplete energy release of boron(B)powder as a metal fuel,the removal of the inherent dense oxide layer(B2O3)on B surface was focused.The recent ad-vances by using metal oxides(MxOy)(e.g.,Bi2O3,CuO,NiO,TiO2,SnO2,MoO3)and metal fluorides(MxFy)(e.g.,LiF,BiF3,FeF3,CoF2)to improve the ignition and combustion performance of B are summarized.The effects of different modifiers on the combustion of B are analyzed,and the advantages and disadvantages of various modified B in terms of ignition and com-bustion performance are compared.The mechanisms of modified B by the modifiers are elucidated.Current challenges are i-dentified,including the need to establish structure-performance relationships between modifiers and B combustion through multi-scale computational simulations from micro-to meso-and macro-scale combined with machine learning models.Furthermore,comprehensive strategies such as synergistic multi-component composite coating,nano-structuring,and novel reactive system design should be pursued to optimize B combustion.These efforts aim to provide a theoretical foundation for achieving effi-cient,controllable,and high-performance B-based fuel systems.Attached with 87 references.
