▎ 摘　　要

NOVELTY - Composition comprises graphite flakes and graphene oxide. USE - The composition is useful for producing graphite block and reinforced graphite block (all claimed). The graphite blocks are used as thick lubrication blocks, low cost electrode replacements for expensive synthetic graphite electrodes, neutron ray filters, and as furnace liners. ADVANTAGE - The graphite block has superlubricity character (claimed), and has high carbon purity. By using the method for producing graphite block, large graphite blocks can be obtained economically and fast. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for: (1) a graphite block comprising graphite flakes and graphene oxide; (2) a reinforced graphite block comprising graphite flakes, graphene oxide and fiber glass or basalt fibers; and (3) a process for producing a graphite block from graphite flakes and graphene oxide, which involves: (a) preparing a graphene oxide solution; (b) mixing the graphene oxide solution with graphite flakes to receive a mixture; (c) heat treating the mixture of step (b) in an increased temperature to remove water and oxygen from the mixture; and (d) compressing the heat treated mixture under pressure to obtain the block.
