WebSep 1, 2024 · 1. Introduction. Highly active metal fuels (Al, B) are used in explosives and propellants can enhance the energy density and combustion performance [1, 2].Boron (B) shows great potential applications due to high calorific value (58.28 kJ/g 136.38 kJ/cm 3), which is 1.9 and 1.66 times of Al [3, 4].However, it is limited by low combustion efficiency … http://boronlubricantsllc.com/products.html Triethylborane is strongly pyrophoric, with an autoignition temperature of −20 °C (−4 °F), burning with an apple-green flame characteristic for boron compounds. Thus, it is typically handled and stored using air-free techniques. Triethylborane is also acutely toxic if swallowed, with an LD50 of 235 mg/kg in rat test subjects. fiche eps cm2
