CerMag FS range
Magnesia/Alumina Spinel Schmelzspinell

A high quality range from alumina-rich to magnesia-rich Spinels, produced by electrofusion of seawater periclase and Bayer process calcined alumina. Applications in the production of steel, glass, cement and ceramic refractories.

Increasing use in the production of technical ceramic shapes with matching of thermal expansion properties where appropriate.

Applications also include use in moulding systems for Titanium casting.

Available in a range of alumina contents from 30 through to 70%.

Major phases identified by X-Ray Diffraction as magnesia-alumina spinel with increasing free-periclase as the MgO increases. Ensures complete control of the chemistry and physical properties promoting complete control of the final ceramic system. Non-carcinogenic Cr2O3 replacement.
