Hey guys! today we talk about, graphite. I think you must hear about graphene. as more and more media are talking about it. Actually the first piece of graphene is directly from graphite. It was found by two British scientists in 2004. they used tape to peel off from graphite again and again. Eventually succeeded in extracting single atom layer graphene. So you will see that the graphene is just a layer of the graphite. The graphite we talked about here. is natural flake graphite. This is graphite mineral. It looks like steel-gray. It feels very light and soft. You even can scrape it off. with your nails, easily. We can grind it into powders. With many different particle sizes for industry purposes. And sizes of flake particles can be controlled during the production. Now let's zoom in under the electron microscope. Wow!! It looks like this. with many flakes, that’s how the name, flake graphite, comes from.
Zoom in again. In the atoms form. Its three-dimensional structure. is stacking of two-dimensional graphene layers. In ABAB sequence. The carbon atoms. Are arranged in a honeycomb lattice. With separation of zero point one hundred and forty two nanometer. and the distance between layers. is zero point three hundred and thirty five nanometer. Bonding between layers. Is via weak van der Waals bonds. which allows layers of graphite to be easily separated. or to slide past each other. That's why graphite is so smooth like oil. when you scratch with your fingers. no doubt. it is naturally. a superior solid lubricator.
Flake graphite has a wide usage in many industries, like refractories, batteries, steel making, expanded graphite, brake pads and brake linings, foundry facings and lubricants. Let’s take brake pads and brake linings as an example. Natural flake graphite is a very important friction modification in its formulation structure, because of its hardness is at the bottom of of Mohs scale hardness table, only between one and two. and what’s more important, is because of its lubrication characteristics. Flake graphite can help to increase the heat conduction, reduce friction wear rate and noise. It is a key element in the brake formulations. Based on the performance requirement, we can add in ten to forty percentage, or even higher of the whole formula. It is quite a huge consumption of the total usage for brake industry.
