Summary

The process for fabricating silicon carbide whiskers via the reaction between silica and carbon was investigated, with the objective of identifying the critical variables controlling the process economics. The fabrication sequence was divided into three basic unit operations: pre-conversion preparation, conversion, and post-conversion quality enhancement. Within each unit operation, baseline cost estimates were determined, and the sensitivity of these costs to critical variables was analyzed using a technical cost model. Variables that were found to be critical to the resulting costs included the starting materials, the annual production volume, and the whisker yield.
