Abstract
High purity metallic arsenic is produced through a process consisting of the chlorination of arsenious acid (As2O3), distillation and then hydrogen reduction.We combine these methods in order to produce 6N-7N5 metallic arsenic.The purity is confirmed by analytical methods such as Emission Spectrographic, SSMS and GDMS.High purity metallic arsenic is used for gallium arsenide (III-V compounds) and arsenic selenide (chalcogenide glass). Gallium arsenide-based devices are developed and manufactured for communications and computing machines. Chaicogenide glass is used in the photoconductor such as a copy machine.High purity metallic arsenic is used for gallium arsenide (III-V compounds) and arsenic selenide (chalcogenide glass). Gallium arsenide-based devices are developed and manufactured for communications and computing machines.Chaicogenide glass is used in the photoconductor such as a copy machine.Investigations on the properties of arsenic compounds such as arsine, arsenious acid and arsenic chloride have made it possible to prepare a high purity arsenic in safety.
