PURPOSE: To obtain the method capable of producing the flaky graphite fine powder excellent in dispersibility into matrices, and in handleability, orientation, etc., by an extremely short time grinding process without deteriorating the original excellent characteristics, such as conductivity, lubricity, corrosion resistance and heat resistance, of natural graphite. CONSTITUTION: This method for producing the flaky graphite fine powder having an average thickness of <=1μm and containing fine partcles having particle diameters of <=1003mm in an amount of >=95vol.%, the improvements comprise immersing swollen graphite in a dispersion medium, roughly grinding the swollen graphite in a swollen graphite concentration of 2-10wt.% based on the whole amount of the swollen graphite and the dispersion medium, and subsequently finely grinding the obtained slurry with a mill having a rotary disk-like grindstone. |
