Flake Graphite for Graphene

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.

Graphenium Flakes are Flake Graphite

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.

Our Specialities

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

Our cleanest flakes are the “Flaggy Flakes”
Range of thickness very thin (approx. 0.010 mm) to thick (approx. 2 mm)
Carbon content 99 – 99.9 %

“Flaggy flakes, extra-large”
These are very clean, thin, and bright shining flakes, approx. 15 – 30 mm long.

“Flaggy flakes, normal”
These are very clean, thin, and bright shining flakes, approx. 5 – 15 mm long.

There are three main differences between our Graphenium and Flaggy Flakes:

• Flaggy Flakes are our cleanest flakes, having undergone no chemical treatment.
• Flaggy Flakes are the thinnest with at least one side being smooth, flat, and possessing a bright, silvery shine. Graphenium Flakes can have thicknesses of up to 2 mm.
• The chances of finding and obtaining mono-crystals from Flaggy Flakes is higher compared to Graphenium Flakes.
