Amorphous graphite is a naturally occurring seam mineral that forms from the geologic metamorphism of anthracite coal. Contrary to the name, ‘amorphous’ graphite is not truly amorphous, but is a microcrystalline form of natural graphite. The morphology of amorphous graphite is typically granular except in extremely fine grinds, which have a flakey structure.
The term “amorphous” is applied to this form of natural graphite because the extremely small “crystallite” particles that make this material do not form crystal faces that are visible to the naked eye (anhedral opposed to euhedral). “As mined” material is available in sizes ranging from mixed 1 cm and smaller particles to 10 cm lumps
(1)Mainly used in pencil making, graphite emulsion for welding rod burden of graphite axle, raw material of battery carbon rod.
(2)Mainly used in Coating in casting refractory material, dye electrode compound, etc.
(3) Mainly used as carbon additive in steel plant, to adjust the content of C in steel.
The nature graphite mining is lacated in North Korea, we import the raw mining material and product the cargo in China. We gurantee the good quality and the cargo is exported in Korea and to Japan widely.
