Effects of Combustion Conditions on the Characteristics of Al2O3/AlB12 Composite Powders Produced by Self-Propagation High-Temperature Synthesis

Abstract

Abstract: Al₂O₃/AlB₁₂ composite powders were produced by self-propagation high-temperature synthesis (SHS) employing Al and
B₂O₃as initial reactants. The effects of combustion conditions on the characteristics of the powders were discussed. The results show that, Al₂O₃
has an average particle size of 3～4μm , while the size of AlB₁₂ is in the submicron range. The composite powders have an average specific surface of
～1 m²/g. Impurities of B₂O₃ and 9Al₂O₃.2B₂O₃ can be observed at the surface of the products because of the evaporization and condensation of B₂O₃.
By decrease the argon pressure in the reactor, Al₂O₃/AlB₁₂powders of high purity can be obtained. The adiabatic temperature of the reaction 13Al+6B₂O₃=6Al₂O₃+AlB₁₂
obtained from thermodynamic calculations is significantly higher than the measured combustion temperature.

Key words: combustion synthesis, Al₂O₃/AlB₁₂ composite, adiabatic temperature
