Scientists and Researchers informed us that our Graphenium Flakes and Flaggy Flakes are best suitable for the preparation of graphene by peeling with large areas.
NGS offers extremely large flakes for peeling from flake graphite ore deposits we discovered in 2006 and 2007. This type of flakes is extremely rare. The name “Graphenium Flakes” was suggested by Professor Sir Geim, who was honoured with the Nobel Prize for his work with our graphite flakes.
Range of high quality, extremely large Graphenium Flakes
Flake size - number of flakes per gram (approx.)
1 – 2 mm not counted
2 – 5 mm approx. 100 flakes/g
5 – 10 mm approx. 25 flakes/g
10 – 20 mm 3 - 8 flakes/g
20 – 25 mm 2 - 3 flakes/g
25 – 30 mm 1 - 2 flakes/g
> 30 mm 1 flake/g
The natural Graphenium flakes are chemically cleaned. Our cleanest flakes are the “Flaggy Flakes”
