Boron‐Based High Explosives

Abstract

The detonation velocity, detonation pressure, and cylinder expansion energy of a series of boron compounds including nitroalkylborates, and mixed amino-nitrosusbtituted borazines, borazenes, iminoboranes, and azaboridines were calculated with Cheetah 2.0. The detonation velocity of the boron compounds is always superior to the allcarbon analogues at the corresponding densities. Nitrosubstituted boron compounds bearing amino groups instead of hydrogen display even higher performance.

Effect of metal hydrides on the burning characteristics of boron

“…Elemental boron has long attracted interest as a fuel for propellants and explosives [1]. Among all chemical elements, boron has the highest volumetric heat of combustion (140 kJ/cm 3 ) and the third highest gravimetric heat of combustion (59 kJ/g 3 ) after H 2 and Be [2].…”

Combustion heat of the Al/B powder and its application in metallized explosives in underwater explosions

“…This means that it is a good choice to add boron powders to metallized explosives to improve the time period and bubble energy in underwater explosions. Many papers have been published on the effects of boron used in explosives [19,20]. For example, it was proved that the boron powder can improve the heat of explosion; there was a linear relationship between the heat of explosion and the content of boron (8-20%).…”

Computational Studies on Nitro, Nitramino, and Dinitramino Derivatives of 1‐Aminoazadiboridine as High Energetic Material

“…The first tactic increases the density of the material whereas the latter is used for increasing the energy content. An emerging trend in developing high energetic materials is the incorporation of boron in organic moieties.B oron based high explosives have recently been reviewed by Koch and Klapçtke [8].T he advantage with Bi st hat aB ÀNu nit is isoelectronic and isosteric with aC =Cu nit (CC/BN isosterism). The isoelectronic nature of C=Ca nd BÀNu nitsa risesf rom the fact that borona nd nitrogen have three and five valence electronsr espectively in their valences hell, and consequently,aBN unit has the same valence electron count (eight electrons) as that of aC Cu nit, in whiche ach carbon contributes four valencee lectrons.…”
