热压碳化硼(B4C)陶瓷

热压碳化硼防弹陶瓷具有低密度，高硬度，高模量高热导率，高熔点，耐磨，自润滑性好、耐酸碱腐蚀、耐辐射、吸收中子等特点，并具有较高的抗弯强度和断裂韧性，是一种综合性能十分突出的新型高性能工程陶瓷材料，在高端防弹装甲材料、高端液气密封材料、航天航空发动机喷头、高端陶瓷轴承、研介质、硬质材料的抛光和精研磨料等方面具有重要用。

Hot pressed boron carbide bulletproof ceramics have the haracteristics of low density, high hardness, high modulus, high thermal conductivity, high melting point, wear resistance, good self-lubricating properties, acid

and alkali corrosion resistance, radiation resistance, neutron absorption,etc., and have high bending strength and fracture toughness. lt is a new type of high-performance engineering ceramic material with outstanding

comprehensive performance. lt has important applications in high-end bulletproof armor materials, high-end liquid and gas sealing materials.aerospace engine nozzles, high-end ceramic bearings, grinding media polishing of hard materials, and precision grinding abrasives.Moreover, it is corrosion-resistant and has good thermal stability, making it a widely accepted fast neutron absorbing material internationally. At present, it is widely used as a shielding plate and neutron absorption core block fornuclear industry atomic energy reactors.
