Passivation Process Improves Anti-oxidation and Moisture Resistance

Ordinary mineral powder is easily oxidized and caked in humid environments and long-term shipping. Our low silicon Ferrosilicon adopts professional surface passivation technology to form a stable protective layer. It effectively resists moisture and air erosion, maintaining stable magnetism and powder state during long storage and marine transportation. It adapts to humid mining areas and long-distance export shipments.
