THERMAL DECOMPOSITION AND DEFLAGRATION OF SOLID BORANEHYDRAZINE
ABSTRAKT
Combustion of BH3.N2H4 has been shown to occur with the 100% formation of the very fine borone nitride. That is considered to be the result of avoiding diffusion difficulties, which are characteristic for heterogeneous systems. Stable combustion of pressed samples in an inert atmosphere was carried out in the pressure range of 20−100 atm. The heat evolved was measured by the calorimetric method. The calculations on the heat of formation and the combustion temperature have been made. Thermal decomposition of boranehydrazine both in the liquid and solid state was studied with the use of mass-spectroscopic analysis. Based on the data obtained, the combustion model was proposed, involving decomposition of boranehydrazine in the condensed phase with the decrease both in density and heat generation due to the foam formation in the burning zone.
