Ferrosilicon

Ferrosilicon is an alloy of iron and silicon with variable silicon content. The most demanding grades on the market are ferrosilicons with 70% to 75% silicon.
Main Application :

• Deoxidizing agent in steel production
• silicon additive for production of silicon steel and High silicon cast iron
• Inoculant agent for grey cast iron

Microsilica

The American Concrete Institute (ACI) defines Microsilica as “very fine non-crystalline silica produced in electric arc furnaces as a by-product of production of elemental silicon or alloys containing silicon” (ACI 116R). Main application:

• Concrete and cements
• Refractory and Ceramics
• Polymer and chemical industry
• Oil well grouting

High purity Ferrosilicon

Ferrosilicon 75% HP (High Purity) is an alloy which is produced by combining around 75% of Silicon and 25% of iron. This product is manufactured from selected raw material with high purity degree and rigorous quality control, which guarantees wide homogeneity among lots. Main application:

• Use of grain-oriented electrical steel
• Use of electrict transformer scores, power generators and other electrict equipment. Chemical composition (weight%)

Ferrosilicon Slag

Ferrosilicon Slag is a by-product when
making Ferrosilicon.

The silicon content is from 40% to 55%, and the rest are Al ,C, S, P, Ca etc.

Ferrosilicon off grade

Ferrosilicon off grade is a by-product
when making Ferrosilicon.

The silicon content is from 55% to 65%, and the rest are Al ,C, S, P, Ca etc.
