Unground calcined Aluminas

Almatis offers a variety of unground calcined aluminas with primary crystal sizes ranging from 0.3 – 25µm. Most of these calcined aluminas are also available in continuous and batch ground versions. Our calcined alumina purity levels range from 99.5 - 99.8%, including normal soda (≤0.35%), intermediate soda (≤0.20%), low soda (≤0.10%) and ultra-low soda (≤0.05%) products.
