Theoretical and Experimental Research on Preparing Silicon Microspheres by Pulsed Electrical Discharge Method

Abstract:

In this paper, a new method of preparing silicon microspheres is introduced. Silicon microspheres have been produced under transient and high temperature generated with pulsed electrical discharge in the liquid. Their micro topography and composition are characterized and analyzed by SEM/EDS. The mechanism of sphere formation is studied by local area temperature field analysis using ANSYS. Various sizes of silicon particles (0.5-30μm) are successfully prepared under the different processing conditions. It is demonstrated that pulsed electrical discharge method is energy controllable, cost-effective, and is of great significance to the preparation of silicon ink which is the important material of new type of TFSC and selective emitter cell.
