Alumina (Al₂O₃) is an aluminium oxide characterised by high hardness and excellent wear resistance. It is widely used for its remarkable thermal, mechanical and chemical properties. Thanks to its stable crystalline structure, alumina offers excellent heat resistance, high hardness and very good chemical stability in aggressive environments.
It is commonly used as a functional filler or technical material in the fields of ceramics, refractories, composites, coatings and advanced technical formulations. Thanks to its unique properties, alumina improves the mechanical strength, thermal performance and durability of materials, even under extreme conditions. Furthermore, alumina is one of the most important abrasives for polishing a wide variety of surfaces.
