Fine-grain boron carbide-silicon carbide composite ceramic with graphene as template and rapid preparation method of fine-grain boron carbide-silicon carbide composite ceramic
The invention relates to a fine-grain boron carbide-silicon carbide composite ceramic with graphene as a template and a rapid preparation method thereof.The composite ceramic is prepared from graphene nanosheets, boron powder and silicon powder as raw materials through a spark plasma sintering method, and the composite ceramic is a compact solid composed of ceramic grains and the ceramic nanosheets, the ceramic nanosheets are stacked to form layered structures, and ceramic crystal grains are uniformly dispersed and distributed among the layered structures. The fine-grain boron carbide-silicon carbide composite ceramic provided by the invention is simple in component, fine in grain and extremely high in bending strength and fracture toughness, and has a good application prospect in the aerospace field as a functional material, such as a wear-resistant ceramic, an impact-resistant material, a bulletproof material and the like.
