Literature review surveys technological foundations for producing ultra-high-purity arsenic across major industrial nations, highlighting historical methods for semiconductor-grade recovery.
This review surveys patent information and fundamental literature sources on the technological foundations of producing high-purity arsenic and its compounds in the leading countries: Russia (USSR), USA, Japan, Germany, and China. The 1960–1979 literature sources on the following issues are summarized:—recovery of elemental arsenic from various raw materials;—production of high-purity (99.99999 wt %) arsenic and its compounds;—devices and equipment for recovery and purification of elemental arsenic and arsenic-containing substances.
