THE PREPARATION OF HIGH-PURITY BORON VIA THE IODIDE,

Abstract

In this paper the present methods of boron preparation are discussed with emphasis on the iodide intermediate. Several methods of boron triiodide preparation were investigated, the most satisfactory method being the preparation from the elements. A yield of 60 pct based on iodine is found for this method. Zone-refining, sublimation, distillation, and fractionalrecrystallization results are given for the boron triiodide, with distillation producing the best results. Several methods of decomposition are also discussed. The purity of the resulting iodide boron approximates the purity of the best available bromide boron. (Author)
