With approximately 700‘000 tons per year China is the world-wide largest producer of natural graphite. More than one third of its production is exported to Europe, the US and to the Middle East. The majority of approx. 30 active mines are located in the provinces Heilongjiang, Shandong and Inner Mongolia. Depending on the origin and the deposit the graphite is qualified for different fields of application.
IEA International Trading maintains a detailed database of all different deposits and nearly all 130 Chinese graphite refineries. This enables us to manage the production of graphite meeting even exceptional customer requirements, e.g. concerning specifications of bulk density or ash composition.
We know the strong points of each graphite mine or refinery. Thus, we are able to offer highest quality grades of graphite. Our suppliers are certified according to DIN ISO and monitored by a continuing quality control.
We are at any time at your disposal for further information.
Micro-crystalline Graphite (amorphous graphite)
Macro-crystalline Graphite (natural flake graphite)
Synthetic graphite is made from a mixture of high-quality petroleum coke, pitch coke and needle coke, after a treatment by mixing, pressing, impregnating, graphitizing, crushing and sieving. The product is used in materials for battery anodes, high quality lubricants, automotive brake pads and many other areas.
Classified according to raw materials:
We offer jet-mill or hammer-mill products with a stable quality of d50 4 micron at very reasonable prices.
We not only offer standard products with 50 MESH and an expansion rate of 250 ml/g, but also some special varieties with low (<160° C) or high (> 250° C) start temperature or extremely low (<30 ml)/g) or high (> 400 ml/g) expansion rate
We can supply you with all grades of coated and uncoated spherical graphite from experienced partners. Details and specifications on demand.
