Fused Magnesia
MgO
High-density fused magnesia supplied for premium refractory bricks, steel furnace linings, and electrical insulation.
Overview
Fused magnesia (FM) is produced by arc-fusion of magnesite above 2800 °C, yielding large periclase crystals of exceptional purity, density, and thermal stability. It outperforms DBM in applications demanding maximum MgO purity, electrical resistivity, and resistance to corrosion by basic slags in premium steel refractories and electrical insulation systems.
