High velocity continuous-flow reactor for the production of solar grade silicon. First quarterly report

PDF Version Also Available for Download.

Description

This program is designed to test the feasibility of a high volume, high velocity continuous reduction reactor as an economical means of producing solar grade silicon. Bromosilanes and hydrogen are used as the feedstocks for the reactor along with preheated silicon particles which function both as nucleation and deposition sites. Efforts have been devoted to the investigation of system design and system materials of construction. A complete reactor system has been designed and fabricated. Initial preheating studies have shown the stability of tetrabromosilane to being heated as well as the ability to preheat hydrogen to the desired temperature range. Several ... continued below

Efforts have been devoted to the investigation of system design and system materials of construction. A complete reactor system has been designed and fabricated. Initial preheating studies have shown the stability of tetrabromosilane to being heated as well as the ability to preheat hydrogen to the desired temperature range. Several test runs have been made and some silicon was obtained from runs carried out at temperatures in excess of 1180/sup 0/K.
