Abstract

Abstract

β-Si₃N₄ fibers were fabricated through combustion synthesis （CS） process.Droplets composed of Si and Al at the tip of fibers were found. It is concluded that the growth of β-Si₃N₄ fibers is controled mainly by VLS mechanism. Hexagonal colummna single crystal β-Si₃N₄ with smooth surface and without any default was also found in the conbustion process of silicon powder. VC process is the controled mechanism for the growth of colummna single crystal β-Si₃N₄.
