Novel rood-like yttrium α-sialon crystalline powders prepared by combustion synthesis

摘要

Novel rod-like yttrium α-sialon crystalline powders were fabricated by combustion synthesis process. The experimental results show that the combustion temperature, the rate of the Si_3N_4 conversion, the nitrogen pressure and the composition of the additives prominently affect the phase formation and microstructures of the resulting α-sialon powders.
