Physical description & handling notes

• Ferrosilicon appears as a solid alloy of iron and silicon. Used to add silicon to iron and steel. Ferrosilicon is an odorless, crystalline solid metal. It is flammable and can react explosively with oxidizing materials. In the presence of moisture or water it may emit toxic and explosive fumes. It is used in magnesium processing.
• Odorless metal; [CAMEO] Grey metallic solid; Insoluble in water; [Globe Metallurgical MSDS]
• 5.4 (USCG, 1999) - Denser than water; will sink
