The invention discloses boron carbide ceramic and a preparation method and application thereof, and belongs to the technical field of weaponry. The preparation method of the boron carbide ceramic comprises the following steps: fully mixing boron carbide powder and carbon nanotubes in proportion, compacting and forming, then carrying out flash sintering-plasma sintering, and in the sintering process, generating nano-diamonds in situ from at least part of the carbon nanotubes, so as to obtain the boron carbide ceramic in which the carbon nanotubes and the nano-diamonds are uniformly distributed. The boron carbide ceramic prepared by the invention has the characteristics of high toughness, high hardness and high strength, can be used for bulletproof decks, and can resist multiple strikes of armor-piercing bullets and armor-piercing incendiary bombs.
一种碳化硼陶瓷及其制备方法与应用，属于武器装备技术领域。该碳化硼陶瓷的制备方法先将碳化硼粉体与碳纳米管按比例充分混合、压坯成型，再闪烧‑等离子体烧结，烧结过程中至少部分碳纳米管原位生成纳米金刚石，得到纳米碳管、纳米金刚石均匀分布的碳化硼陶瓷。本发明制得的碳化硼陶瓷具有高韧性、高硬度、高强度的特点，能够用于防弹甲板，可抵御穿甲弹、穿甲燃烧弹的多次打击。
