What is ferro silicon used for?

Steel deoxidizer:
Ferro silicon reacts with oxygen to form silicon dioxide, which removes oxygen from molten steel, prevents oxidation of molten steel, and improves the quality and performance of steel.
Alloy additive:
When added to steel as an alloying element, it can improve the hardness, wear resistance, and corrosion resistance of steel, and is often used in the production of special steel grades such as spring steel, bearing steel, and tool steel.

Aluminum Alloy Additives:
Added to aluminum alloys to improve their strength, hardness, and heat resistance, these additives are commonly used in the production of aluminum alloy components for the aerospace and automotive manufacturing industries.
Magnesium Alloy Treatment Agents:
Used in the smelting process of magnesium alloys, these agents purify the magnesium alloy liquid and improve its casting and mechanical properties.

Silicon Compound Production:
Ferro silicon can be used to produce silicon compounds such as silane, silica sol, and silica gel. These products are widely used in industries such as coatings, rubber, plastics, and electronics.
Chemical Reducing Agent:
In some chemical reactions, ferro silicon can be used as a reducing agent to reduce metal oxides or other compounds.

Semiconductor Materials:
High-purity ferro silicon is the main raw material for producing semiconductor silicon wafers, which are used to manufacture electronic components such as integrated circuits, transistors, and diodes.
Electronic Packaging Materials:
Ferro silicon powder can be used as a filler in electronic packaging materials to improve their thermal conductivity and mechanical strength.
