Calcined Aluminas

At ITAFORTE, we offer high quality calcined alumina, an essential and versatile material that plays a crucial role in several industries, such as ceramics, steelmaking, refractories, polishing, investment casting, glassmaking, among others.

Our portfolio includes a range of calcined alumina-based products, which are key to improving the quality and performance of industrial processes. Whether to increase the mechanical resistance of ceramics or improve the durability of refractory coatings, ITAFORTE's calcined aluminas are a superior choice, guaranteeing excellence in your applications.

Aluminum oxide, known as alumina, is a chemical compound with the formula Al2O3, produced from the calcination of hydroxide of aluminum. This hydroxide is extracted from bauxite using the Bayer process. The most common and stable phase of alumina is alpha (α-Al2O3), which has a hexagonal crystalline structure, making it extremely resistant and suitable for high-performance industrial applications.
