Calcined Alumina - MZK

The Martinswerk MZK is an unground, low soda calcined alumina utilized in a variety of industrial applications. The MZK is used for structural ceramics, compounds, fillers, and refractory applications. Designed for shaped refractory products subjected to extremely high mechanical, thermal, chemical and electrical loads.

For low soda -325 F grade go to MZK-3.
