Zentek Ltd (formerly known as ZEN Graphene Solutions and before that, Zenyatta Ventures) is a mineral exploration and development company based in Ontario, Canada. Zentek is developing the Albany Graphite Deposit â a rare hydrothermal graphite deposit with the potential to produce a natural, high-purity graphite that may compete in high-technology markets traditionally reserved for synthetic graphite.
The company's high crystallinity graphite can be upgraded without the use of aggressive acid (HF) or high temperature thermal treatment. Zentek has developed an environmentally friendly metallurgical process flowsheet that consists of grinding, flotation and caustic treatment using sodium hydroxide. The company states that it has been able to achieve an extraordinary carbon purity result of >99.9 percent in bench-scale tests, using this proprietary and environmentally friendly purification process.
According to Zentek, current end uses for its graphene materials include composites (concrete, rubber and plastics), energy storage and environmental applications but many more are under development.

Zentek and Pattern Energy to collaborate on icephobic technology for wind turbine industry
Zentek has announced a collaboration with Pattern Energy Group to optimize, test and validate Zentek’s icephobic coating for the wind turbine industry. The partnership is being supported financially by both the Natural Sciences and Engineering Research Council of Canada (“NSERC”) and PRIMA Quebec - Advanced Materials Moving Forward.
Pattern Energy develops, constructs, owns, and operates wind turbines and understands the lost efficiency and potential damage to the wind turbine itself and its surroundings that comes from ice accretion on these structures.
Zentek updates on graphene-based icephobic technology for drones
Following its September 2022 announcement on testing of icephobic coating technology, Zentek has now reported successful drone testing, where thrust was maintained under calibrated icing conditions of freezing drizzle and freezing rain in an outdoor, real-world environment. The drone with Zentek's icephobic coating applied to the propeller blades hovered under the outdoor icing rig and, on all tests conducted, maintained flight until the end of the battery life of the drone. The same drone with uncoated propeller blades rapidly lost the ability to maintain flight, according to the Company.
Zentek shared that the coating is a functionalized graphene oxide augmented elastomer.
