Boron Carbide Block Description
Boron carbide blocks are bulk inorganic non-metallic materials made from high-purity boron carbide powder as the core raw material, with a small amount of sintering aids added, through batching and mixing, compression molding, high-temperature sintering at 1800-2200℃, and precision processing. They have outstanding performance advantages: a Mohs hardness of 9.3, second only to diamond and cubic boron nitride, with wear resistance far exceeding that of ordinary metals and ceramics; a density of only 2.52g/cm³, much lower than steel, combining high strength and lightweight characteristics; they also possess excellent chemical stability, being able to resist corrosion from most acids and alkalis, and have excellent neutron absorption capacity, which can effectively shield nuclear radiation. Based on these properties, they are indispensable in many key fields: they can be processed into bulletproof inserts and protective components for armored vehicles, used as neutron shielding parts and control rod components in nuclear reactors, and also made into wear-resistant valves, sandblasting nozzles and other mechanical parts, making them high-performance functional materials for cross-field applications.

FAQ
What's used to make boron carbide blocks?
Core material: high-purity boron carbide powder (plus small sintering aids). Process: batching → molding → 1800–2200℃ sintering → precision machining.
Why use the boron carbide block for bulletproof armor?
Extreme hardness (Mohs 9.3) resists penetration, and low density (2.52g/cm³) keeps armor lightweight.
How does the boron carbide block shield nuclear radiation?
Its boron-10 isotope strongly absorbs neutrons (key in nuclear radiation), used for reactor shielding and spent fuel storage.
How is the boron carbide block better than steel for wear resistance?
Harder (Mohs 9.3 vs. steel’s 5–6) and more corrosion-resistant (resists most acids/alkalis), no rusting.
Is the boron carbide block stable at high temperatures?
