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

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 , [92] is a superior abrasive.
