High Purity Alumina

AEM is using its patented Chlorine Leach, Crystallization Purification (CLCP) process to manufacture high purity alumina (HPA) at up to 99.999% purity (“5N”) at its production plant in Cap-Chat, Quebec, marketed under the SupALOXTM brand. The Cap-Chat plant is currently in trial production and AEM plans to ramp it usp to full production in early 2022.

The effectiveness and high resource efficiency of the CLCP process combined with the availability of renewable hydroelectricity in Quebec puts SupALOXTM high purity alumina well ahead of the market in terms of both purity and environmental performance, while maintaining a competitive price.

AEM is also planning to commission a new SupALOXTM production plant in the United Kingdom, based on a next generation design, by the end of 2023. AEM is receiving financial support from the British Government's Automotive Transformation Fund in taking these plans forward.

HPA is an extremely pure form of aluminium oxide that is valued for its chemical stability, very high melting point, high mechanical strength and hardness, and good thermal conductivity but high electrical insulation. It is a strategically important speciality mineral, which commands premium prices.

It is used to produce synthetic sapphire, which is essential for the manufacture of LEDs, semiconductors and “state of the art” optical devices. Its unique physical and chemical properties also have critical uses in phosphor compounds and advanced ceramic coatings.

HPA thus has uses in many disruptive, high growth technologies where purity determines demand, price and application.

With its exceptional high purity, AEM  is marketing SupALOXTM high purity alumina primarily to the manufacturers of synthetic sapphire for use in the emerging Micro-LED industry, and of ceramic coated separators for the electric vehicle lithium-ion battery industry, which represents the largest potential growth market for HPA demand in the coming decade.
