Evaluation of selected chemical processes for production of low-cost silicon. Phase III. Eighteenth quarterly progress report, January 1-March 31, 1980

PDF Version Also Available for Download.

Description

Progress during this report period was marked by the initial operation of the Process Development Unit at about 50% of design capacity with indications that many aspects of the facility operated satisfactorily. However, a downstream constriction, the cause of which is being isolated, led to termination of the run after one-half hour of operation. In the light of observations made during earlier start-up efforts, several modifications of equipment and technique were made for improved operation. Vacuum outgassing experiments (850 to 1100/sup 0/C, 1 to 256 h) were carried out on miniplant-produced granules containing 360 and 3900 ppMw of zinc in ... continued below

Description

Progress during this report period was marked by the initial operation of the Process Development Unit at about 50% of design capacity with indications that many aspects of the facility operated satisfactorily. However, a downstream constriction, the cause of which is being isolated, led to termination of the run after one-half hour of operation.

Vacuum outgassing experiments (850 to 1100/sup 0/C, 1 to 256 h) were carried out on miniplant-produced granules containing 360 and 3900 ppMw of zinc in the deposited silicon. Treatment of the data so that it can be extrapolated to the expected product of the Experimental Process System Development Unit awaits development of an appropriate model.
