Magnesia Alumina Spinel
Magnesia–alumina spinel is a ceramic phase used to improve thermal shock resistance and corrosion behavior in refractory systems.
Description
It can be introduced as pre-formed spinel or generated in situ from MgO and Al2O3 sources. Selection considers chemistry, grain size, and compatibility with basic or alumina matrices in the intended lining design.
Applications
- Component in cement kiln and steel ladle linings
- Castables requiring moderated thermal expansion
- Tailored blends for chemical compatibility with slags
Packaging
- Sealed bags or drums on pallets with batch identification
- Prevent contamination and moisture ingress
- Avoid impact that may alter grain size distribution
Storage
- Store dry and covered; reseal after opening
- Segregate by lot to maintain formulation consistency
- Use FIFO for multiple deliveries
