Albany Graphite Corp. produced ultra-pure 5N graphite meeting nuclear standards, advancing clean energy and battery tech.

Albany Graphite Corp., a Zentek Ltd. subsidiary, achieved a second ultra-high purity 5N graphite batch (99.9992 wt.% carbon) from its Albany deposit using a halogen-free electrothermal fluidized bed reactor process. The material met nuclear industry standards with an equivalent boron concentration of 2.60 ppm, below the 3 ppm threshold, indicating suitability for reactor applications. The process, operating at 2,800°C, offers a cost-effective, environmentally safer alternative to traditional methods. Ongoing tests assess particle size, compressibility, resistivity, and friction, while near-net-shaped graphite bricks are being developed for reactor lining. Additional evaluations explore use in lithium-ion battery anodes and cathode additives. These advancements support global nuclear energy growth, including Canada’s Darlington SMR project and U.S. efforts to expand domestic nuclear capacity, highlighting the potential of natural Albany graphite as a reliable, high-purity material for clean energy and advanced battery technologies.
