Abstract
This paper reports results of studies aimed at developing physicochemical and technological principles of the preparation of ultrapure, 99.99999 wt % (7N) arsenic from standard (As2S3 sulfide ore) and unconventional raw materials (lewisite warfare detoxification products) using directional solidification as a final step in the arsenic ultrapurification process. Using different purification processes, we have obtained and investigated experimental batches of high-purity arsenic.
