摘要：

Nano-sized beta-silicon carbide (beta-SiC) powder was successfully prepared using the combustion synthesis method in air in combination with a controlled pre-reaction mechanical activation treatment. For the low-exothermic reaction system Si/C, the effect of the mechanical activation time, one crucial processing variable, on the combustion behavior of Si-C reactant in air was investigated, and the reaction kinetics parameters were measured and calculated to analyze the reaction mechanism of this combustion reaction. Meanwhile, the reaction mechanism was further approved by the thermodynamic calculation. (c) 2008 Elsevier Ltd. All rights reserved.
