Abstract

Si₃N₄ is one of the most promising structural ceramics due to its unique properties, while the large scale applications are still limited by its high cost and low reliability. Combustion synthesis (CS) is a feasible approach to synthesize Si₃N₄ in large scale and low cost. This work focused on the mechanism of CS Si₃N₄ during commercial production process.
Temperature profile analysis of the on-line measured data indicates that the conversion ratio was only 40% when the combustion reaction temperature reached the highest value. Post-combustion nitridation could last as long as 660 s. A model was proposed to account for the combustion synthesis of α-Si₃N₄, the CS process was optimized to regulate the phase composition and particle size of the combustion-synthesized product.
