The goal of this work was to determine the origin of phosphine gas (PH^sub 3^), which has been reported to be generated from wet, commercial ferrosilicon alloys containing ~75 wt pct Si. Based on previous work, it is suspected that PH^sub 3^ evolves when phosphides present within the alloy react with atmospheric moisture or water. Reactive phosphides have been identified in synthetic ferrosilicon alloys, which contain higher amounts of phosphorus than are typically present in commercial alloys. Therefore, reactive phosphides in commercial FeSi75 alloys are expected to be important to the evolution of PH3 from these alloys. To identify the role of reactive phosphides in the evolution of ...
