Atomized Ferrosilicon (FeSi) is Atomized ferrosilicon (FeSi) is a powder produced by rapidly cooling molten FeSi alloy into fine particles using a gas or liquid atomization process. This process results in particles with a high surface area and specific properties that make them suitable for various industrial applications, especially in mineral processing and metallurgy. Key aspects of atomized FeSi:
Production:
Atomization involves rapidly cooling molten FeSi by spraying it with a high-pressure gas (like nitrogen or argon) or liquid (like water). This rapid cooling creates fine, spherical particles.
Particle Size:
Atomized FeSi typically has a wide range of particle sizes, often between 212 microns and 20 microns, according to an industrial supplier.
Properties:
Atomized FeSi exhibits properties like high specific gravity, magnetism, corrosion resistance, and good fluidity. The spherical shape of the particles is also a notable characteristic, according to an industrial supplier.
Applications:
Dense Media Separation (DMS): Atomized FeSi is used in DMS to separate minerals based on their density, according to Mineral-Loy.
Welding Electrode Coating: Atomized FeSi can be used as a coating in welding electrode production.
Steelmaking: It can be used in steelmaking for adjusting, inoculating, suspending, coating, and deoxidizing purposes.
Other Industries: It's also used in casting, melting, mineral processing, semiconductor production, and the production of silicon copper. . This process results in particles with a high surface area and specific properties that make them suitable for various industrial applications, especially in mineral processing and metallurgy.
