The invention belongs to the technical field of ceramic materials, and particularly relates to a silicon nitride ceramic cutter, and a preparation method and application thereof. The silicon nitride ceramic cutter with a high-precision arc blade, a chip breaker groove, surface patterns and other complex shapes can be prepared, the cutting resistance is reduced, and the cutting efficiency is improved; the silicon nitride powder is doped with a sintering aid, so that the fracture toughness and the strength of silicon nitride ceramic can be effectively improved; and according to the silicon nitride ceramic cutter, and the preparation method and application thereof, the technical problems that in the prior art, a silicon nitride ceramic cutter with a high-precision chip breaker groove used for improving the cutting efficiency and a surface pattern structure cannot be prepared, and the silicon nitride ceramic cutter is high in preparation cost and short in service life can be effectively solved. 本申请属于陶瓷材料的技术领域，尤其涉
