High Purity (>99.9%) Graphite Nanopowder and Micropowder

A naturally occurring form of crystalline element carbon with versatile applications from lubricants to nuclear reactors

Overview | Product Information | Related Products

Graphite (CAS number 7782-42-5), one of the most stable forms of carbon under standard conditions, is a naturally occurring form of crystalline element carbon.

Graphite powders possess many unique physical and chemical properties such as refractoriness, high structural strength at high temperature, high thermal shock resistance, high thermal and electrical conductivity, low thermal expansion, and good chemical resistance. Graphite has both metallic and non-metallic properties and is readily soluble in iron. The combined unique property of graphite makes its wide applications from common pencils, zinc-carbon batteries, lubricants, paints, welding rods, desulfurizing agents, facings, refractories, marking instruments, batteries, bearings, conductive coatings, and crucibles to electrodes.

With such high purities, graphite powders are also suitable for liquid exfoliation or intercalation to either produce single layer/few layers graphene nanosheets or fill the spaces with cations i.e., Li+ between the layers of graphite.

The atoms in graphite (right) have bonds extending in only 2 dimensions, so when it is cut in an orientation parallel to the bonds, none of them are broken.

More on Graphite Powder

The carbon atoms in graphite are linked in a hexagonal network which forms sheets that are one atom thick. The sp2 hybridized graphene layers are linked by rather weak van der Waals forces and π–π interactions of the delocalized electron orbitals. These sheets are poorly connected and easily cleave or slide over one another if subjected to a small amount of force, giving graphite a very low hardness, perfect cleavage, and slippery feel, which is opposite to the hard feel of diamond (sp3 bonding).

Graphite Pricing

Prices for +80 mesh large flake exceeded US$1,300/t in the late 80s but crashed to US$600-750t in the 90s as Chinese producers dumped product on the market. During this period there was essentially no exploration and no new mines were built in the west. Graphite prices did not start to recover until 2005 and well surpassed US$1,300/t with large flake selling for up to $3,000/t in early 2012 with some shortages reported. Price appreciation was largely a function of the commodity super cycle and the industrialization of emerging economies as new, high growth applications such as Li ion batteries (“LiBs”) had not yet had an impact on demand or consumption.

After peaking in 2012, graphite prices experienced a sharp drop due to the slowdown in the Chinese economy and a lack of growth in western economies. Since that time they have been sideways to down as the market waits for continuing growth in the EV and the lithium ion battery industries to use up excess capacity in China.

The capacity issue was exacerbated by the commissioning of a large new mine in Africa. The mine was well over budget, only operated at 50 or 60 per cent of design capacity and was consistantly cash flow negative until being shut down. This has caused some of the surplus production capacity in China to be used up. However, substantial new sources of supply are urgently needed if the expectations of automobile and battery makers are to be even partially realized.

Lithium ion batteries are now approaching 50 per cent of graphite demand and continue to grow rapidly even though the uptake of EVs has been slower than anticipated. Almost all battery anode material is made in China from small flake graphite because it is plentiful and cheap. The current picture for large flake prices is much better as Chinese production is declining, the African operation does not produce much and demand is growing.

Benchmark Mineral Intelligence estimates that the major auto makers have committed over US$300 billion to developing EVs and that there are over 200 LiB mega-factories in the pipeline. These factories represent over 3,000 gWh of LiB production capacity which in turn equates to over 1,000,000 tonnes of new annual graphite demand by 2025. In short, graphite production has to more than double quickly to meet this demand. As a result, the outlook for graphite prices is very bright and the need for secure western sources of supply is critical.
