    MRL receives outstanding results from graphene testing

    Results provide significant boost to the already-robust economics of MRL’s high-grade Sri Lankan graphite projects MRL Corporation (ASX: MRF) is pleased to advise it has received outstanding results from the test work conducted on its Sri Lankan graphite and its properties for scalable graphene production. Key observations made in the report presented to the Company were;
     The tests were conducted to check for the amenability of the ore for single step extraction of graphene.  The quality of the prepared graphene from MRL’s graphite is outstanding and comparable with the quality of graphene prepared by synthetic routes.
     MRL’s graphite has very high crystalline carbon content not observed in any other previously tested graphite materials.
     A number of processes were tested with electrochemical exfoliation providing the best results. This process route was stated to be scalable and therefore suitable for commercial scale production of single and few layered graphene directly from the graphite ore.
     The Company will now consider the merits of producing both graphite and graphene in its development plan. Discussions will be initiated with a number of research organisations to optimise that route to production. Combined Thermal and Mechanical Process This method is used to isolate graphene directly from raw graphite (after milling) and without having to produce graphene oxide. This test generated single layered graphene sheets with excellent quality and low defects, which was confirmed by the Raman shift curve. The quality of graphene prepared by this method is comparable with graphene prepared by the synthetic method and the best quality graphene available on the market from few suppliers
