| Research Abstract |
Tribromosilane recovery reaction of vaporized tetrabromosilane with hydrogen gaseous has been monitored by mean of online gas chromatography in a flow reactor system. The tetrabromosilane conversion was reached to about 50 % at 700 C. An experiment with tetrachlorosilane under the same conditions led to a decrease in tetrachlorosilane conversion efficiency. This demonstrates that recovery reaction from tetrabromosilane to tribromosilane is energetically favorable compared to that of tetrachlorosilane, as predicted from the thermodynamic calculation for the pseudo first order reaction in a flow reactor. Finally, the rate constant for overall recovery reaction at 550 C and 600 C was measured to be 0.0162 /s and 0.128 /s, respectively.
