Flake Graphite

Micronized Flake GraphiteGreat Lakes Graphite works with partners to fulfill purchase orders for micronized natural flake graphite to customers located in North America and around internationally. We micronize high quality natural flake, sourced from Brazil, to standard sizes between 5 and 75 microns. Product can be made to your exact particle size specifications, whether it’s a single size or a blend of multiple sizes. Please see the Products section of the website for more information on available micronized graphite products: Shop Graphite.

Synthetic Graphite

Great Lakes Graphite produces micronized high quality, high purity synthetic graphite products through a partner located in the Eastern United States. This material is used in a variety of applications and is available in sizes that range between 5 and 45 microns.

These products are available now and are being delivered in quantity to customers in the drilling and steel industries.


Ashland Advanced Materials plant in Niagara Falls, NY.Ashland Advanced Materials has an ISO9001-certified facility, located just a few miles from Niagara Falls.

Great Lakes Graphite and Ashland Advanced Materials, LLC have formed a partnership to jointly manufacture high purity micronized graphite products, at an industrial scale. Capabilities to manufacture coated spherical purified graphite (CSPG) are currently being evaluated. Access to large volume purification capabilities creates a strong competitive advantage for Great Lakes Graphite as the Company joins the energy storage and lithium-ion battery market supply chains.

The partnership provides a number of benefits, including the following:

  • Baseline purification cost data and material for customer sampling have been generated.
  • Niagara facility is optimally located to benefit from well established battery-related initiatives in upstate New York, including the recently opened Battery Commercialization Center.
  • Great Lakes Graphite has established a partnership with Ashland Advanced Materials, LLC, a privately-owned, leading provider of graphitized carbon products, headquartered in Niagara Falls, New York. The partnership is focused on high volume purification of micronized flake graphite. Towards this end, Great Lakes Graphite and Ashland have executed a Memorandum of Understanding that establishes a framework for now moving towards a definitive agreement that will formalize the terms of the partnership.

Senior Vice President of Sales Mike Coscia said, “We are extremely fortunate to have a partner with the advanced, industrial-scale graphite purification capabilities that Ashland offers. Equally as valuable is the accumulation of knowledge and experience by the Ashland team which is a critical resource in our joint development efforts. The initial purification work we have done together is providing baseline cost data and also high purity micronized graphite material for our customer sampling program.”

The partnership will seek to leverage Ashland’s Niagara location by connecting to ongoing economic development initiatives that are well-established in the region. In January 2017, New York Governor Andrew Cuomo announced Buffalo Billion Part 2, a continuation of a major state commitment to economic development in the Buffalo-Niagara area. Among other things, that initiative is targeting funding for strategic advanced manufacturing projects.

The State of New York has a highly supportive infrastructure for building a battery-related business.

New York State has made a significant commitment to becoming a global leader in battery technology through investments in the New York Battery and Energy Storage Technology Consortium (NY-BEST) headquartered in Albany, New York ( and the Battery Commercialization Center that recently opened in the Eastman Business Park in Rochester, New York (

Matt Reineke, President of Ashland Advanced Materials, LLC, said, “We are excited about working with Great Lakes Graphite on graphite purification. We have gotten to know the team over the past year of working together and believe that there is a significant opportunity for high purity micronized graphite for a number of rapidly-growing markets. The Great Lakes team has proven themselves to be solid partners, resourceful and capable and well-aligned with our long held commitments and values that have Ashland Advanced Materials the successful enterprise that it is today.”

Great Lakes Graphite Chief Executive Officer Paul Gorman said, “This partnership represents a watershed moment for the company. We have in Ashland Advanced Materials, a partner who represents a crucial link in the graphite value chain and a link that is indispensable to the manufacture of graphite material for lithium-ion battery anode usage. We are grateful to have a partner with truly world-class capabilities, a strategically-located facility that has all of the required infrastructure and an unparalleled wealth of knowledge regarding advanced carbon purification technologies. We will be sharing more information about development work we have been jointly conducting as those results become available.”

Innovation and Technology Development

Great Lakes Graphite constantly pushes the envelope in an ongoing effort to manufacture and deliver the highest quality and most innovative products to our customers as well as to create a sustainable competitive advantage.

graphite slurryIn accordance with these goals, Great Lakes Graphite and NanoSpire, Inc. announced a joint product development effort in July 2017. NanoSpire is a privately-owned US company that has developed the next generation of particle sizing technology based on its patented technology which harnesses cavitation microjets to resize virtually any material into particles as small as a few nanometers.

Great Lakes Graphite believes this partnership will yield a number of competitive advantage. NanoSpire’s unique technology holds the potential to deliver greater process accuracies and efficiencies as well as innovating entirely new products. The Company believes there is tremendous value in the ability to consistently produce high quality carbon materials in volume, within a tight size range at the nanometer scale.
