Products Refractory Industry Fused MC-Spinel

Product Information - Fused MC-Spinel


Fused magnesium chromium oxide is a synthetically produced material for the refractory industry.
It is a mixture of magnesium oxide (caustic magnesia) and chromite/chrome ore concentrate or chromoxyde, which is melted in an electric arc furnace.
As it cools, fine spinel crystals are formed with the structure Mg(Cr,Fe)2O4 which are evenly distributed in the periclase structure of the excess magnesium oxide.
The magnesium chromium oxide is then coarsely crushed into fragments (0-approx. 40mm) or crushed into standard fractions, sieved and ground for use in refractory blocks and compounds (e.g. in RH processes and for the lining of cement rotary kilns).

Magnesium chromium oxide is characterised by high corrosion-resistance against base impurities and high resistance against temperature changes.
