NABALOX® – Calcined and Reactive Aluminas for any Refractory Application

Nabaltec is a worldwide leading and large scale producer of synthetic raw materials for a wide range of application areas, such as the refractory industry.
NABALOX®, our range of high performance aluminas offers significant advantages in their refractory applications. Their high purity of 99,5% – 99,7% Al2O3 as well as their sophisticated particle size distributions make them the perfect raw materials for refractories with highest packing density and excellent refractoriness under load.

Standard aluminas with Top Cut provide very low water demand at an outstanding price performance ratio.

In shaped and unshaped refractory applications, the reactive NABALOX® special aluminas are characterized by an extremely reproducible and homogeneous processability. NABALOX® reactive aluminas enable a wide processing window and a significant reduction in water demand. This class of reactive aluminas lowers the production costs and raises the efficiency of the refractory solutions by improving packing density, corrosion resistance and durability of refractory materials.

In modern refractory applications, niches can be found, where highest demand for thermomechanical properties meets the necessary for easy workability. State of the art reactive aluminas commonly need a compromise between a.m. properties. So highest refractoriness resp. slag resistance can be achieved with lowest water demand but followed by extremely dilatant castable viscosity or the need for vibration.

The new generation of NABALOX®, viscosity optimized reactive aluminas, allow the combination of both, lowest water demand and practice compatible consistency. The new developed, viscosity optimized reactive Alumina NABALOX® NO 530 allows the formulation of free flowing castables with water demands below 4%, without the drawback of high dilatancy. Thus, mixer loads can be increased and mixing time can be reduced.

Our newest innovation, NABALOX® NO 550 P, with its trimodal particle size distribution allows the same, but for pumpable refractories.
