| Research Abstract |
In the present study, we investigated the effect of heating temperature and evaporation rate of sodium (Na)on the formation of the Si crystal fibers. By heating disk of compacted NaSi powder at 800℃, the grain growth of the Si crystals was observed and the Si crystal fibers were formed on the Si disk surface. The purified Si grains were obtained by using low-purity Si powder as a starting material.
