Hexagon Resources, in collaboration with the University of Adelaide, has announced a breakthrough in producing graphene using a flake graphite sample from its McIntosh project. Results from this study indicate that Hexagon’s graphite has potential to be used for graphene production.
These graphene test work results will be sent to commercial graphene groups. Company representatives stated that "The key driver will be the capacity to produce commercial quantities of graphene. These exceptional test work results achieved from a bulk scale representative sample from McIntosh gives Hexagon that capacity.
The graphene was able to be produced from Hexagon’s ultra-high purity graphite and was successfully demonstrated using all three exfoliation methods. A high yield of graphene was extracted from graphite at approximately >90%. The graphene was produced via several methods including a ‘green method’ without the use of hazardous chemicals.
