Combustion and thermal decomposition of hydrazine borane

Burning rates of hydrazine borane at a pressure of 20–100 atm have been measured. Spectroscopic and electron microscopic studies have demonstrated that the condensed combustion product is a fine powder of boron nitride. Thermal decomposition of hydrazine borane has been studied. The obtained kinetic data and physicochemical properties of the materials and the foam combustion model have been used to calculate the pressure dependence of the burning rate of hydrazine borane, which agrees with the experimental one. The obtained degree of conversion of the material to boron nitride indicates the possibility of using hydrazine borane and similar compounds in high-performance systems.
