abstract |
In this paper, Yb alpha-sialon powders with elongated grains have been prepared by combustion synthesis. The effects of diluents, nitrogen pressure, adding alpha-sialon seeds and NH4F on the phase transformation and microstructure development of the samples are discussed systematically. The experimental results show that the addition of diluents, proper nitrogen pressure and additive NH4F can facilitate the nitridation of Si. It was also found that the added alpha-sialon seeds and NH4F are beneficial to the nucleation and growth of elongated grains. |
