Purification method of boron carbide micro-powder, boron carbide ceramic and preparation method of boron carbide ceramic
The invention discloses a boron carbide micro-powder purification method, a boron carbide ceramic and a preparation method of the boron carbide ceramic. The boron carbide micro-powder purification method comprises the following steps: carrying out homogenizing grinding, vacuum heat treatment purification and secondary grinding on the basis of commercially available W3.5 series boron carbide micro-powder raw material, and carrying out drying and powdering on boron carbide slurry in a spray granulation mode. The boron carbide ceramic is composed of the following components: boron carbide micro-powder, liquid carbon black, submicron aluminum nitride micro-powder, a titanate coupling agent, water-soluble phenolic resin, water-soluble acrylic acid glue, polyethylene glycol, glycerol, deionizedwater, whisker type multi-walled carbon nanotubes and Ti--Si-C ternary MAX phase micro-powder. The preparation method of the boron carbide ceramic comprises the following steps: weighing the components, carrying out high-speed ball-milling pulping, carrying out spray granulation, pressing a green body, and carrying out pressureless sintering. The problem that in the prior art, the purity of boroncarbide micro-powder is not high is solved, and meanwhile pressureless sintering preparation of the boron carbide ceramic is achieved.
