Mar 09, 2014· Boron Carbide (B4C): The most expensive ceramic used in armor, and the second hardest material on Earth (behind diamond), it is also much lighter than Alumina. This material is used in the highest-end rifle plates, and can be enhanced with new methods (such as sinterless pressing) to achieve nearly theoretical density (meaning there are no ...

Capability to sinter ceramics, especially carbides, at low temperature, is desired but is a challenge. Recently, cold sintering has been successfully demonstrated with oxides and other ceramics, but not with carbides due to high thermodynamic and chemical stability. In this work, low‐temperature sintering of boron carbide (B 4C)

The microwave pressure sintering can also be applied on many applications beside boron carbide. The applications areas include refractory ceramics, ceramic cermets, composites, et al.. In addition, many new material systems that were not available or hard to achieve by conventional techniques can be designed and fabricated by this technique.

Aug 14, 2019· Pressureless Sintering . Boron carbide ceramic materials have strong covalent bonds (more than 90%), coupled with the poor shaping of boron carbide, large resistance to movement of the product boundary, and small surface tension in solid state, making boron carbide ceramics a kind of material that is not easy to sinter. When sintering at atmospheric …

Boron carbide (B 4 C) ceramics were synthesized by spark plasma sintering at a temperature between 1600 and 2050 °C without employing any sintering additives.
