If you’re unsure about Boron Carbide powder, you will have to understand that it’s one of the hardest materials. The substance may bear physical and chemical characteristics similar to diamonds. Since it appears black or gray colored the powder is often referred as ‘black diamond’. The substance is not just unscented but additionally insoluble in water.
Characteristics of Boron Carbide Powder
The compound is tough boron-carbon ceramic that’s broadly contained in industries, in producing bulletproof vests, and tank armors. Acquiring a hardness calculating around 9.3 over the Mohs scale, the compound is recognized one of the hardest materials after cubic boron nitride and jewel. The Elastic Modulus and fracture toughness would be the characteristics closer to values for jewel.
Because the primary substance is solid anyway, the powdered form is produced while using the chemical reaction between Co2 and Boron oxide. Since the thermal reduction appear in an electric arc furnace, the powder needs to be refined through different ways. After removing metallic impurities, the powder becomes suitable for commercial use. Get in touch with Boron Carbon suppliers whenever you intend to purchase the substance.
Similar to other non-oxide materials, boron carbide is tough to sinter. But, 90 five percent density can be achieved using hot pressing or hot isostatic pressure sintering. To achieve sintering within the temperature between 1900 and 2200 levels Celsius, the compound ought to be together with bit of Plastic Carbide or fine Carbon.
Quite interestingly, Boron Carbide includes a high mix sectional area that’s capable enough to absorb neutrons. Besides, the substance offers stability when chemicals and radiations need to be ionized. The compound also functions just like a p-type semiconductor characterised by hopping-type transport. Since the band gap is equivalent to 2.09 eV, mid-band gap states make photoluminescence spectrum harder.
Thus far because the molar mass is anxious, the compound is 55.255 g/mol acquiring a specific gravity of two.52. The melting point is 2763 °C (5005 °F) because the boiling point is somewhere closer to 3500 °C. Apart from other physical characteristics, the substance features a density calculating 2.52 g/cm3.
When the substance reaches its usual condition, the material features a rhombohedral crystalline structure. Because within the attribute, several variants might be thought without any modification of structure. The carbon content may vary till a maximum of 17 %. To know more information on the material, talk to a Boron Carbide manufacturer.
Applying Boron Carbide Powder
Due to its hardness, Boron Carbide functions as an abrasive when materials must be polished. It is also contained in producing cutting tools and applications like jet water cutting. Since the materials are abrasion resistant, it is also located in the manufacturing of nozzles.
Wealthy in strength, low density and elastic modulus the material may be used in ballistic armors. The choices help in protecting individuals from high velocity projectiles.
