Boron Carbide - Precision Ceramics
Boron Carbide can be machined in green, biscuit, or fully dense states. While in the green or biscuit form it can be machined relatively easily into complex geometries. However, the sintering process that is required to fully densify the material causes the Boron Carbide body to shrink approximately 20%.
Introduction and appliion of boron carbide
Properties: boron carbide is a solid harder than silicon carbide or tungsten carbide. It was used as a kind of coarse sand grinding material a long time ago. Because of its high melting point, it is not easy to cast into artificial products, but through high temperature melting powder, it can be processed into a simple shape, used for grinding, grinding, drilling and polishing of cemented

Herein we reported a new method for preparing BN by low-temperature CVD using ammonia borane as precursor on silicon carbide fibers. Ammonia borane was sublimated at 110–130°C using a heating belt, and the sublimated gaseous substance was transported to the deposition region where the silicon carbide fibers were placed at the deposition temperature of 900°C.

Boron - Wikipedia
Boron carbide and cubic boron nitride powders are widely used as abrasives. Boron nitride is a material isoelectronic to carbon . Similar to carbon, it has both hexagonal (soft graphite-like h-BN) and cubic (hard, diamond-like c-BN) forms. h-BN is used as a high temperature component and lubricant. c-BN, also known under commercial name borazon ,  is a superior abrasive.
