抄録

In order to prepare pure silicon by the iodide process, the purification of crude SiI4 by the recrystallization and distillation methods has been examined. By the use of quartz vessels and organic solvents including toluene, n-heptane and benzene in the recrystallization mothod, Ti, Al, and Cu, etc. were removed in a few repeats. Distillation in an all-quartz, 13 theoretical plate column packed with Fenske ring was found to be effective in eliminating Cu, Mg, and Mn etc. and most impurities were found in the residual part of the still.
