Reactive Aluminas

Reactive aluminas are specially designed for the production of high performance refractories where defined particle packing, rheology and consistent placement characteristics are as important as the superior physical properties of the final product. Reactive aluminas are fully ground down to the primary (single) crystals by highly efficient grinding processes. The average particle size, D50, of mono-modal reactive aluminas, is therefore nearly equal to the diameter of their single crystals. The combination of reactive aluminas with other matrix components, such as tabular alumina 20μm or spinel 20μm, allows the control of the particle size distribution to achieve the desired placement rheology.
