Never miss the golden opportunity to dig-up the world’s best vein Graphite and seeking the best Graphene products from Sri Lankan graphite.
As previously stated, Sri Lanka’s Ragedara Graphite mine was the world number 1 mine in terms of producing graphite until the end of the Second World War. Graphite from Ragedara produces the purest vein graphite in the world and the leading global supplier for Nano-materials (Analytical Reports of Superior Graphite and SGS).
The uniqueness of Ragedera vein graphite creates a great demand for it for its enormous applications at present. by following the standard “quality material inputs always creates quality products”, Ragedara mine is now producing quality Graphene (Reduced Graphite oxide-rGO) and Graphene oxide-GO from a unique graphite source.
What is Graphene ?
By following the standard “quality material inputs always creates quality products”, Ragedara mine is now producing quality Graphene (Reduced Graphite oxide-rGO) and Graphene oxide-GO from unique graphite source.
Graphene is a single layer of graphite known as the Wonder Material today and it is the building block of graphite. Graphene can be produced through chemical and/or physical exfoliation of graphite. Chemical exfoliation of graphite produces graphene oxide and reduced Graphene Oxide which are highly valuable materials.
Properties of Graphene Graphene has high thermal conductivity and electrical conductivity, high elasticity and flexibility, generate electricity through exposure to sunlight, extraordinarily light weight and strong and is a transparent material.
Ragedera rGO Facts (SEM, XPS, FTIR and Raman Analysis)
Reduced Graphene Oxide (rGO)
Ragedera graphite mine produces rGO using two steps. Chemical exfoliation of graphite involves oxidation of graphite to produce graphite oxide and/or graphene oxide (GO) followed by Reduction of GO to produce graphene. The reduced product often is referred to as ‘Reduced Graphene Oxide (rGO)’ instead of ‘graphene’. Since rGO consists of a reduced oxygen content. rGO finds more or less similar applications as graphene.
rGO consists of1-6 layers, BET surface area : 398 m2 g2
