Boron carbide is an excellent armor material with a decades-long history of use, but bulk diamond effectively renders it obsolete. Bulk polycrystalline diamond tiles are many times harder than boron carbide, many times tougher, many times stronger, and, ultimately, have a firm performance edge.
Boron carbide (B 4 C) is one of the world's hardest manufactured materials. Its strong chemical bonds and hard surface minimize wear in rigorous environments. Boron carbides are often used in ballistic armor, taking advantage of exceptional hardness and low density. The hardness provides excellent protection, while the light-weight maximizes ...
For example, custom-made ceramic panels made of boron carbide or hot-pressed boron carbide plates are used for pilot seats in helicopters. Other uses and areas of application of boron carbide Boron carbide powder is a starting material for sintering and hot pressing in the manufacture of boron carbide sintered parts .
