Boron Carbide

Introduction of Boron Carbide

Boron carbide (B4C) is an inorganic nonmetallic material with excellent performance, which is synthesized at high temperatures by the combination of boron and carbon.The hardness of B4C materials are second only to diamond and cubic boron nitride, and thry have excellent chemical and physical properties. With the explosive development of 3D printing technology, a wider range of materials can be printed now. Recently, B4C materials have also begun to be applied in the field of 3D printing. As shown in Fig. 1, a qualified 3D printing (FDM) test piece with B4C-PEEK composites.

CD BioSciences is a technology company dedicated to providing 3D printing solutions, not only the metal and plastic 3D printing materials, but also the hard B4C materials, and can customize composite materials with B4C according to your needs.

B4C materials have the advantages of low density, high melting point and temperature resistance, semiconductor conductivity, chemical stability, and are one of the hardest materials known, so they are often used to manufacture products with excellent wear resistance. In addition, B4C materials have high neutron absorption capacity that other ceramic materials do not possess, which are proven to be tolerated radiation, so B4C materials are important in bulletproof and armor systems. However, due to the high cost and difficulty of sintering B4C materials, it is difficult to prepare B4C parts by traditional ceramic processes. Machining B4C materials with 3D printing technology can more effectively use B4C manufacturing parts and achieve the required complex shapes in a shorter time, which is conducive to the further development of B4C materials in different fields.

The B4C 3D printing materials provided by CD BioSciences are one new type of ceramic materials with outstanding comprehensive properties, which can be composed of composite materials with other materials to meet the needs of different industries.
