▎ 摘　　要

NOVELTY - The preparation method of silicon carbide pyrolytic graphene involves (1) cleaning a silicon carbide substrate, and placing in an annealing frame, and (2) growing graphene with uniform thickness on a surface of the silicon carbide substrate by silicon carbide high temperature thermal decomposition method. USE - Preparation method of silicon carbide pyrolytic graphene. ADVANTAGE - The method enables preparation of silicon carbide pyrolytic graphene with uniform thickness and excellent repeatability, by simple, economical and industrial process.
