Hexagon Resources: Graphene Produced from McIntosh Project Graphite

Hexagon Resources (ASX:HXG) reported that graphene was successfully produced from Hexagon’s high-purity graphite from the McIntosh project. Furthermore, leading Australian University test work has produced a bulk scale representative sample of graphite.
As quoted in the press release:

Graphene:

• Graphene produced from Hexagon’s ultra-high purity graphite (+99.9%TC) was successfully demonstrated using all three exfoliation methods
• High yield of graphene from graphite at approximately >90%
• High quality graphene with single to a few layers from Hexagon’s graphite samples is confirmed by Raman, TEM and TGA analysis
• Graphene produced via several methods including a ‘green method’ without the use of hazardous chemicals
• Graphene produced from Hexagon’s high-purity graphite samples have comparable quality to graphene currently available on the market
• These graphene test work results will be sent to currently engaged commercial graphene groups

Graphite:

• Elemental composition after combustion of Hexagon’s bulk scale flake graphite sample confirms ultra-high purity material grading +99.9 %TC
• X-Ray Diffraction (XRD) has confirmed that the carbon in the representative bulk scale graphite concentrate is crystalline with no amorphous material
• Results from this study indicate that Hexagon’s ultra-high purity graphite has the potential to be used for large scale graphene production
