As a metallic silicon, it withstands extreme thermal cycling, maintaining structural integrity and minimizing contamination of molten metal. Used in steel, copper, and nickel smelting, it improves slag fluidity and protects refractory bricks from erosion. Our product is produced with low iron, calcium, and aluminium content to avoid unwanted reactions in aggressive melts. This ensures longer service life of refractory systems and consistent alloy chemistry. Supplied in lump or granular form, it integrates easily into industrial processes. Manufacturers benefit from enhanced furnace reliability, reduced downtime, and consistent quality in high‑temperature metallurgy operations.
