Boron Carbide

by Schunk Technical Ceramics

Boron carbide is a non-oxide ceramic characterized by a particularly high hardness, a high modulus of elasticity and good wear resistance at low weight. The reaction-bonded RBB₄C (at Schunk CarSIK-B₄C) is used in particular in the ballistics sector. The ceramic combines exceptionally high hardness with low density and is thus optimally suited for lightweight solutions in personal protection and for lining land and air vehicles.

What distinguishes CarSIK-B4C?

CarSiK-B₄C, which was specially developed at Schunk for ballistic protection, is a mixed quality of RBSiC and RBB₄C and is optimized for the various ballistic threat classes. In Schunk's CarSIK-B₄C, boron carbide particles are embedded in a silicon carbide matrix. The unique, patented structure gives the material an exceptional degree of hardness and ballistic protection to break and erode even hard core projectiles made of steel or tungsten carbide.

Where is CarSIK-B4C used?

As an overall composite with suitable fiber backing, CarSIK-B₄C exhibits high impact resistance, which gives the protective plates high durability. In the defense & ballistics industry, boron carbide is unrivaled and irreplaceable. For the efficient production of close-tolerance, dimensionally accurate components made of boron carbide, Schunk Ceramics relies on modern and flexible manufacturing processes. In this way, die casting or isostatic pressing are used to create excellent products at a consistently high, reproducible quality level for prototype and series production. This consistency in geometry and material properties is appreciated by our customers worldwide. More than 1,000,000 plates supplied speak for themselves.
