• Synthesis of graphene nanoflakes by grinding natural

     · Natural graphite is a soft material that conventional milling methods fail to grind into nanoparticles. We found that adding NaCl into graphite during milling allows obtaining graphene nanoflakes of about 50 200 nm 2 as evidenced by Transmission Electron Microscope (TEM). NaCl particles are substantially brittle and harder than graphite serving as milling agents by both helping to

     · Graphite is also a good solid lubricant but its lubrication properties vary with the grade of graphite. However for some graphite workpieces the aqueous solution is indispensable when processing on a centerless grinding machine. In this case it is better to use a rust-proof aqueous solution instead to clean the surface of the parts.
