A study was recently completed on bulk scale material from Hexagon Resources’ McIntosh Project. Elemental composition after the combustion of Hexagon’s flake graphite sample confirms ultra-high purity material grading +99.9% TC. X-Ray diffraction has confirmed that the carbon in the representative bulk scale graphite concentrate is crystalline with no amorphous material.
Test work at an Australian leading University on Hexagon’s ultra-high purity graphite produced a high yield of graphene at approximately 90%. This high quality graphene with single to a few layers was confirmed by Raman, TEM and TGA analysis. It can be produced via several methods including a ‘green method’ without the use of hazardous chemicals.
Results from this study indicate that Hexagon’s ultra-high purity graphite has the potential to be used for large scale graphene production.
