Ambient temperatures.
Insoluble in water.


Ferrosilicon 75 is used is mainly used to add silicon to iron and steel. It is also used in magnesium processing, in steelmaking and foundries as a source of silicon in production of carbon steels, stainless steels, and other ferrous alloys for its deoxidizing properties, to prevent loss of carbon from the molten steel, for manufacture of silicon, corrosion-resistant and high-temperature resistant ferrous silicon alloys, and silicon steel for electromotors and transformer cores. In manufacture of cast iron, ferrosilicon is used for inoculation of the iron to accelerate graphitization. In arc welding, ferrosilicon can be found in some electrode coatings. Ferrosilicon is a basis for manufacture of prealloys like magnesium ferrosilicon (FeSiMg), used for modification of melted malleable iron, FeSiMg contains between 3-42% of magnesium and small amounts of rare earth metals. Ferrosilicon is also important as an additive to cast irons for controlling the initial content of silicon.


Keep in a cool, dry, dark location in a tightly sealed container. Incompatible with oxidizing agents.
