Premium Boron Carbide B₄C Powder - High-Performance Ceramics from China Suppliers and Factory
Nuclear Industry
The boron-10 (¹⁰B) isotope, which is abundant in boron carbide, has an extremely high thermal neutron absorption cross-section. This makes it an ideal material for components such as control rods, shutdown rods, shielding materials, and spent fuel storage racks in nuclear reactors, used for controlling and absorbing neutron chain reactions.
In addition to absorbing neutrons, its high hardness and wear resistance also make it suitable as a shielding structural material to protect personnel from radiation.
Grinding, Polishing, and Cutting Tools
Boron carbide powder is widely used in the manufacture of abrasive paste, sandblasting (shot blasting) abrasives, free abrasives (used for grinding cemented carbide, gemstones, ceramics, precision components, etc.), as well as abrasive particles for grinding wheels, whetstones, and abrasive blocks.
As additives or coatings for carbide, they can significantly improve the hardness and wear resistance of tools and are used for machining high-hardness materials.
Semiconductor Fabrication & Wear-Resistant Parts
Boron carbide ceramics or composites are used to manufacture components in various extreme wear environments, such as nozzles (for sandblasting, waterjet cutting), seals, bearings, valve spools, liners (for conveying slurry, cement, etc.), hot extrusion molds, etc. Its excellent wear resistance can greatly extend the life of the component.
High-purity, ultra-fine boron carbide powder can be used for precision grinding and polishing of semiconductor wafers (such as silicon wafers), as well as surface treatment of hard disk substrates.
Additive Manufacturing (3D Printing)
Boron carbide powder is being explored for use in additive manufacturing technologies such as laser sintering and binder jetting, enabling the direct fabrication of complex-shaped boron carbide ceramic components, including lightweight armor, wear-resistant parts, and neutron absorbers, thereby overcoming the challenges associated with traditional ceramic forming and processing.
