Production oh high purity nano alumina from aluminous clay

High-purity nano alumina (HPA) has diverse applications in batteries, LED lights, semiconductors etc. In recent decades, several methods have been developed to produce highly reactive and pure alumina at nano scale. Amongst them, microwave (MW) assisted-based methods have been considered promising. The MW-assisted method can avoid the challenges of other methods by enhancing the energy efficiency of ball milling processes, and enhancing the gelation speed in sol-gel and precipitation processes. The distinctive advantages of MW-assisted processes come from the fact that different materials have varied responses to microwave irradiation, influenced by their structural characteristics. We investigate two MW-assisted processed for producing nano HPA along with their scale-up potential. AEM plans to verify the final product regarding the purity, specifications, and suitability as starting material for applications like ceramics. Following the result of this project, AEM aims to establish a sustainable supply chain for nano alumina in North America, fostering synergy across various actors in the EV materials supply chain.
