| Outline of Final Research Achievements |
Bromination of silicon with and without a wear metal or alkali metal has been investigated in a flow reactor under various conditions. All the silicon-impurity mixture reacted with HBr to form bromosilanes, irrespective of the presence and absence of the impurities. The reactivity of each Si sample was evaluated with respective to the HBr conversion. Metal impurities in the silicon samples were dramatically reduced in the products. The addition of impurities did not cause any increase in impurities. Rather, it resulted in an improvement of the activation energy or reactivity of HBr, maybe as a result of better heat transfer in the reactant and surface reaction field. This demonstrates that the hydrobromination reaction is effective to extract pure bromosilane or silicon from kerf loss silicon even where metal, alkalimetal and abrasive grain are present.
