Preparation method and application of boron-rich boron carbide material
The invention provides a preparation method of a boron-rich boron carbide material. The method comprises the following steps: adding boron carbide micro-powder into an ethylene glycol solution containing a surfactant, adding expanded graphite, and carrying out ball milling; after vacuum drying, putting into a muffle furnace, carrying out vacuum heating, mixing the obtained graphene-loaded B4C particles with boric anhydride and magnesium powder, briquetting, igniting in argon by adopting an electric heating tungsten wire, cooling to room temperature in vacuum after reaction, soaking for 3-5 hours by adopting concentrated hydrochloric acid, centrifugally washing to obtain B13C2-loaded B4C particles, heating in vacuum, introducing inert gas, and cooling to room temperature to obtain the boron-rich boron carbide material. The material has high density and bending strength, and is beneficial to the application of the material in body armor materials.
