Alumina (Al₂O₃)
Alumina matters both as a strategic industrial material in its own right and as the gateway to aluminium supply chains. It has broad industrial relevance beyond primary smelting.
Extreme Hardness
Excellent wear resistance
Thermal Stability
Maintains strength at high heat
Electrical Insulation
Non-conductive properties
Chemical Inertness
Highly resistant to corrosion
Industry Applications
Aluminium Smelting
The primary feedstock for producing lightweight, durable aluminium metal.
Refractories
Provides extreme heat resistance for industrial furnaces and kilns.
Abrasives
Used in grinding wheels and sandpapers for its exceptional hardness.
Advanced Ceramics
Utilised in ballistic armour, wear-resistant components, and cutting tools.
Chemical Processing
Serves as an inert carrier for catalysts in petrochemical refining.
Water Treatment
Activated alumina acts as a highly effective filter for fluoride and arsenic.
Extraction & Future
Alumina is predominantly refined from bauxite ore using the Bayer process. Beyond its traditional use in aluminium smelting, high-purity alumina (HPA) is increasingly vital for the production of LED lighting and lithium-ion battery separators.
Fodere’s process unlocks alumina from alternative resources and industrial residues, offering a greener, circular pathway.
