Scope and purpose
Fine-reactive alumina is intended for the production of high-quality refractories, where the specified particle packing, rheology and consistency during laying are just as important as the properties of the final product.

- Excellent sintering activity and a carefully controlled particle size distribution down to the submicron series give special properties to refractory materials due to:
- optimal particle packing and low water demand for unformed refractories;
- the formation of a strong ceramic bond and, as a consequence, increased wear resistance and mechanical strength;
- higher “hot” strength when replacing fine-ground components with lower refractoriness.
