▎ 摘  要

NOVELTY - A graphene ceramic product contains 0.2-0.5 pts. wt. graphene, 75.5-80.8 pts. wt. kaolin, and 15 pts. wt. zirconium oxide. USE - Graphene ceramic product (claimed). ADVANTAGE - The graphene ceramic product has excellent abrasion resistance, hardness and tensile strength. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of graphene ceramic product, which involves adding graphene and kaolin to zirconium oxide, uniformly mixing, stirring the mixture and then placing in a ball mill, ball milling the mixture, adding water to the mixture and then grinding into powder with a fineness of 500 mesh, precipitating the powder to obtain a precipitate and then extracting, drying the mixture for 40-50 days, adding soil to the mixture and then placing in a reaction machine, uniformly mixing, refining the mixture and then drying at 30-40 degrees C, sintering the mixture at 1200-2000 degrees C for 4-12 hours, and naturally cooling.
