Fused Magnesia

Fused Magnesia

Fused magnesia (FM) is produced by smelting of calcined magnesia in electric arc furnaces at above 3000°C. Fused magnesia is considered to be one of the best thermal and electrical insulators with high density, high purity and large crystals. Kümaş produces fused magnesia with capacity of 37.500 tonnes per year.

FM can be used in;

- High performance MgO-C refractory bricks for steel industry,

- Fired refractory bricks for cement and glass industry,

- Heating elements industry

Fused Mag-Chrome

Fused mag-chrome (FMC) is produced by smelting of calcined magnesia and high purity chromite together. FMC is used in;

  • Refractory bricks for nonferrous metal industry,
  • RH Snorkel refractories
