METHOD OF REVEALING GRAPHITE STRUCTURE

摘要

FIELD: process engineering.SUBSTANCE: graphite surface is faced in circular motion on grinding gauze with openings filled with fine graphite and/or facing product wastes. Then, said surface is ground by diamond paste in circular motion on smooth surface of paper sheet to produce permanent path lubed with grinding products for surface to be finished. Then, lap is etched in etching agent containing the following components in wt %: iodine - 0.5-1.5 and acetone as solvent making the rest, for 2-6 seconds to reveal micro- and macro structure. This is performed by accelerating circular motion of cotton tampon evaporate the solvent. In etching, lap surface is finished and cleaned of etching products.EFFECT: higher validity of graphite structural state definition.1 tbl, 3 ex
