B4C grinding ball- Spherical boron carbide
Product Details
B4C is a noteworthy ceramic material that has been widely used in civil, aerospace, and military fields. The most prominent feature of B4C is its extraordinary hardness (Mohs hardness of 9.36, microhardness of 55GPa~67GPa), which is second only to diamond and cubic boron nitride. In addition, boron carbide has a low density (2.52g/cm3), a high melting point (2450 ° C), and high high-temperature strength, good chemical stability (boron carbide generally does not react with chemical reagents at room temperature, and only slowly corrodes in a mixture of hydrofluoric acid sulfuric acid and hydrofluoric acid nitric acid, making it one of the most chemically stable compounds). B4C has excellent neutron absorption capacity, excellent thermoelectric performance (140s · m-1, room temperature), and a low coefficient of expansion (5.0x10-K-1). Therefore, B4C can be used to prepare bulletproof armor, cutting tools, special acid and alkali resistant materials, thermocouples, and atomic reactor control and shielding materials. In addition, due to its excellent performance, researchers have also begun research on boron carbide coatings.
Boron carbide grinding balls have high hardness, with a Vickers hardness of over 2800HV and minimal wear. If used for grinding boron carbide materials, it is very suitable because the raw material of the product is high-purity boron carbide, which hardly introduces impurities during grinding.
Regarding the production of ceramics, the company has two processes: pressureless sintering and hot pressing sintering. Products with different processes have different advantages and are suitable for different scenarios. Pressureless sintered ceramics have high cost-effectiveness and are suitable for mass production. They are suitable for use as bulletproof materials, seals, nozzles, wear-resistant and temperature resistant materials, as well as common nuclear power materials. Ceramics produced by hot pressing sintering are suitable for small-scale production, can be made into larger sizes, and are suitable for use as nuclear power core materials, semiconductor materials, target materials, and bulletproof materials.
