Description
Magnesia-spinel filler ZH-30 is a high-quality refractory material based on periclase (MgO) and synthetic magnesia-alumina spinel, designed for the production of refractory concretes, masses and mortars that operate in high temperatures and aggressive environments.
The material is characterised by high thermal stability, resistance to slag and metal melts, as well as structural stability under repeated thermal loads.
