The invention relates to a high-wear-resistance low-electrostatic SiC (silicon carbide) ceramic panel for a paper machine, which belongs to the technical field of paper machine accessories and is made by assembling SiC ceramic blocks with a frame. The SiC ceramic blocks are connected with one another through leads, and each SiC ceramic block is made by ingredient preparation, forming, sintering, cooling and processing and includes, in weight percentage, 75-85% of silicon carbide, 8-15% of silicon powder, 5-10% of carbon powder, 1-3% of calcium silicate and the balance rare earth materials. The SiC ceramic panel is conductive and has resistivity lower than 0.3 omega m. The SiC ceramic panel is high in density, low in porosity, high in wear resistance, conductive, and capable of statically absorbing particles and eliminating scratches of a polyester wire mesh by the particles, so that the service life of the polyester wire mesh is prolonged, stoppage and maintenance time is reduced, materials are saved, and con
