Lightweight high-performance boron carbide-based bulletproof ceramic and preparation method thereof
The invention discloses lightweight high-performance boron carbide-based bulletproof ceramic and a preparation method thereof. The lightweight high-performance boron carbide-based bulletproof ceramic is prepared from, by weight, 100 parts of boron carbide powder, 3-15 parts of multiphase additive powder, 50-60 parts of water, 0.1-1.5 parts of a dispersing agent and 2-5 parts of a binder, and gas the density of 97-99%, the bending strength of 420-500 MPa, the fracture toughness of 4.2-4.6 MPa.m<1/2>, and the Vickers hardness of 30-33 GPa. The preparation method comprises the steps of powder mixing, slurry preparation, spray granulation, blank pressing, sintering molding and sintered blank sand blasting treatment. According to the invention, the light high-performance boron carbide-based bulletproof ceramic with the smooth surface is obtained, the sintering activity of a boron carbide powder material is effectively improved, the sintering temperature is reduced, the cost of the sintering machining process is reduced, and the quality of mass production of products is stable.
