NOVELTY - Preparing silica gel modified wood-based silicon carbide ceramic material comprises (1) weighing wood powder, silicon powder and silica gel, and calculating the total mass after weighing, and using, (2) weighing graphene oxide, the mass of graphene oxide is 1-5% of the total mass, and mixing the weighed graphene oxide with the silica gel, mixing the wood powder and the silicon powder, stirring uniformly, and drying in an oven to obtain a first mixture, (3) using first mixture obtained in the step (1), separately subjecting to pre-heating or drying, and subjecting the sample obtained after the treatment to a sintering reaction under the protection of nitrogen, and the silica gel-modified wood is prepared after the reaction based silicon carbide ceramic material. USE - The method is useful for preparing silica gel modified wood-based silicon carbide ceramic material.
