Preparation and Characterization of Monosized Germanium Micro Particles by Pulsated Orifice Ejection Method

Abstract:

Article Preview

Monosized germanium micro particles are prepared by a newly developed Pulsated Orifice Ejection Method (POEM). The obtained particles are categorized into two kinds of the microstructures as refined and coarse ones. The morphological difference is estimated to be determined by the undercooling level during nucleation. Actually, the increase in the temperature of the melt was effective in coarsening the microstructure, because the temperature of the melt intensely relates to the undercooling level. The transition temperature of coarse and refined microstructures is found to be 1300-1350K. Furthermore, a triggered nucleation could improve the crystallinity of the particles in the short separation.
