Hexagonal Boron Carbide Ceramic Armor Plate B4C
– 재료: | B4C / 붕소 탄화물 |
– 소개: | 탄화붕소 (B4C) is one of the world’s hardest manufactured materials. Its strong chemical bonds and hard surface minimize wearin rigorous environments. Boron carbides are often used in ballistic armor, taking advantage of exceptional hardness and lowdensity. The hardness provides excellent protection, while the light-weight maximizes mobility. 추가적으로, the uniquely structured boron carbide can be used for neutron shielding. |
– Typical Characteristics: | 1. Exceptional Hardness 2. Out Standing Wear Resistance 3. 낮은 밀도 4. High Flexural Strength 5. Neutron Absorbing |

Boron Carbide Ceramic Armor Plate
B4c powder (also known as black diamond) is the third hardest material after diamond and cubic boron nitride. It is a suitable material for many high performance applications due to its attractive combination of properties. Its outstanding hardness makes it a suitable abrasive powder for lapping, polishing and water jet cutting of metals and ceramics. The combination of low specific weight, high hardness and reasonable toughness makes it a suitable material for body and vehicle armor. Boron carbide is also extensively used as control rods, shielding materials and as neutron detectors in nuclear reactors due to its ability to absorb neutrons without forming long lived radionuclide. As it is a p-type semiconductor, boron carbide can be a suitable candidate material for electronic devices that can be operated at high temperatures. Boron Carbide is also an excellent p-type thermoelectric material.

Boron Carbide Machining & 연마
Boron Carbide Ceramic Armor Plate
Boron Carbide can be machined in green, 비스킷, 또는 완전히 조밀한 상태. 녹색 또는 비스킷 형태이지만 비교적 쉽게 복잡한 형상으로 가공할 수 있습니다.. 하지만, the sintering process that is required to fully densify the material causes the Boron Carbide body to shrink approximately 20%. This shrinkage means that it is impossible to hold very tight tolerances when machining Boron Carbide pre-sintering. 매우 엄격한 공차를 달성하기 위해, 완전히 소결된 재료는 다이아몬드 공구를 사용하여 가공/연삭해야 합니다.. 이 과정에서는 매우 정밀한 다이아몬드 코팅 도구/휠을 사용하여 원하는 형태가 만들어질 때까지 재료를 연마합니다.. Due to the inherit hardness of the material, 이는 시간이 많이 걸리고 비용이 많이 드는 프로세스일 수 있습니다..
