Alabama Graphite Reports Additional Naturally Occurring Graphene Derivatives Found at Its Coosa Property in Alabama, USA
May 14, 2015 (Source: Marketwired) — Alabama Graphite Corp. (“Alabama Graphite” or the “Company”) (TSX VENTURE:ALP)(OTCQX:ABGPF)(FRANKFURT:1AG) (WKN:A1J35M) (ISIN:CA0102931080) is pleased to announce that it has found additional types of naturally occurring graphene-based derivatives called few-layer graphene (2-5 layers), multi-layer graphene (2-10 layers), and graphite nanoplates (less than 100 nm thick) at its Coosa Property in Alabama, USA. This material was obtained using the same cost- effective process, as was previously used by the Company to obtain graphene (see press release dated March 12, 2015). These types of graphene-based derivatives are valued because they exhibit unique electrical, optical, mechanical, and thermal properties. This work was conducted by Dr. Nitin Chopra, Associate Professor at The University of Alabama under our sponsored research partnership.
Graphene is not only the strongest material known to man (200 times stronger than steel and lighter in weight), but is also one of the most flexible. “These graphene-based derivative materials hold promise for uses in exciting new applications such as thermal management, structures, coatings, power storage, transparent conductive films, conductive inks, structural electronics and sensors,” said Dr. Chopra. “The prime interest is in the observation of electron thin flakes of graphite (also referred as few-layer graphene, multi-layer graphene, or graphite nanoplates) in various mesh sizes (#50-#400) from the Company’s Coosa material. These sizes contain significant importance for advanced graphene/graphite applications because current scientific findings anticipate that as the flake thickness changes, the properties of the material also change. Such size-dependent behavior is commonly observed in synthetic graphene and its derivatives but having a natural counterpart could provide the potential to overcome the existing fabrication challenges associated with synthetic graphite nanoplates/multi, or few-layer graphene.”
Today the biggest challenge with synthetic graphene is the way it is currently produced, which is produced using a variety of expensive, tedious methods that do not lend themselves to large-scale production and are prone to produce defective graphene with uncontrolled flake size. Current synthetic methods for developing graphene include chemical vapor deposition (CVD), mechanical exfoliation, solution exfoliation, and chemo-mechanical methods. This implies higher costs including greater energy consumption and extended manufacturing time.
“We are very excited about finding these additional types of graphene derivatives on our Property as it continues to enhance the potential business dimensions of our project. Work is ongoing on commercial scalability of our naturally occurring graphene and graphene-based derivatives. We are encouraged by the potential of developing natural alternatives to synthetic quality graphene derivatives at a lower cost,” said Ron Roda, CEO of Alabama Graphite.
An item of technical significance is that these graphene derivatives can be referred to as electron transparent due to the ability of these flakes to be visualized under a transmission electron microscope (TEM). Typically, a truly thick graphite flake (>100 nm) will not be visualized under a transmission electron microscope. Furthermore, the greater the electron transparency of a graphite flake, the closer the characteristics of such graphite to that of graphene as long as the flake is defect-free.
Various graphene-based derivatives found by the Company are shown in Figure 1. These flakes being electron transparent were easily observed in TEM and many flakes were oriented orthogonal to the electron beam and allowed for estimating the number of layers in a specific graphene derivative. The Company and Dr. Chopra continue to jointly develop methodologies to isolate various graphene-based derivatives and explore more novel architectures of graphitic carbon.

About Alabama Graphite
Alabama Graphite Corp.’s mission is to become one of the greenest graphite producers in the world. The Company, through its wholly-owned subsidiary, Alabama Graphite Company Inc., is conducting exploration and development both at its flagship Coosa Graphite Project in Coosa County, Alabama, USA and the recently acquired Bama project in Chilton County, Alabama, USA. These two advanced-stage projects are 100% owned by Alabama Graphite and are on private land. The two projects encompass over 43,000 acres and are located in an area with significant historical production of crystalline flake graphite. The Company has the largest NI 43-101 indicated flake graphite resource in the United States based on drilling 0.18 square miles (0.3% of the total acreage). The Alabama deposits are unique in that a significant portion of the graphite-bearing material is oxidized and has been broken down into an extremely soft rock. Both projects have in place critical infrastructure, are within close proximity to transportation routes and enjoy a hospitable climate allowing for year-round production and delivery.
