The invention discloses a ceramic chopper material. The ceramic chopper material is prepared from the following components by weight percent: 65-92.99% of matrix ceramics, 0.1-30% of auxiliary ceramics, and 0.1-30% of additive. The matrix ceramics is at least one of aluminum oxide and zirconium oxide. The auxiliary ceramics is at least one of zirconium oxide, chromium oxide, erbium oxide, niobium pentoxide, zinc oxide, iron oxide, titanium oxide, calcium oxide, magnesium oxide, silicon carbide, strontia oxide, barium oxide, silicon nitride, and tungsten carbide. The invention further discloses a ceramic chopper made of the ceramic chopper material. The invention further discloses a preparation method of the ceramic chopper material. The ceramic formed by the ceramic chopper material prepared by the method has high hardness, high density, small average particle size, good toughness, and excellent wear resistance, and the crystalline particles are difficult to drop in use. The preparation method of the ceramic chopper material is simple, and can be used for industrial mass production.
