Abstract

The high heat of combustion makes boron and metal borides attractive as a metal fuels additive in solid propellants and hybrid fuels. The formed liquid B2O3 oxide layer on the boron particles during the combustion prevents complete combustion and results in a higher burning time of the particles. Aluminum borides are characterized by a high melting point and when heated in an oxidizing environment they are oxidized to form Al2O3 and B2O3 oxides. This study investigates the chemical activity of metal powders based on aluminum, boron and titanium, which can be used in high-energy materials as fuel additives. The paper presents TG-DSC data of Al, AlB2, AlB12, TiB2 powders: The onset temperatures of oxidation and the intense oxidation temperatures of the powders, the conversion coefficient and the weight gain of the samples in the air temperature range of 400-1200 °C. The maximum oxidation rate were obtained for AlB12 powder (0.0104 mg/s) in the temperature range of 774-860 °C.
