Why boron carbide has high hardness?

What is Boron Carbide?

Boron carbide is also known by the name black diamond. It’s an organic substance that has the formula B4C and which is often a grey-black powder. It is one the hardest materials known (after cubic boron Nitride and diamond) and it is used in body armor, tank armour and other industrial applications. Boron carbide has an Mohs hardness of about 9.5. Boron carbide does not react with any acid or alkali solution, so it is insoluble even in water. Boron carbide is also known for its strong thermal neutron capture and high neutron absorption capabilities, which makes it a neutron absorber.

How is boron carbonide used?

Boron carbide can be used as an artificial rigid material. It is second only to cubic boron and diamond. Boron carbide crystals are hexagonal in structure. 2.52g/cm3 is the density. The melting temperature of Boron carbide is 2450°C. It quickly melts at temperatures above 2800°C and then it volatilizes. Boron carbide resists acid and alkali corrosion. It is also not wetted by most molten materials. Boron carbide can withstand air oxidation of 1000 degrees Celsius, however it will oxidize in an oxidizing atmosphere above 900 degrees Celsius. Boron carbide powder can grind at more than 50 percent of its silicon carbide counterpart, which is 12 to the grinding capability of corundum. The boron carbide is extremely versatile and can be used to grind many materials, including ceramics. Under certain conditions of oxygen, it forms protective layers of carbonaceous substances, keeping them from excessive oxidation.

Why are boron carbide and borid so difficult?

Boron carbide can be used to make body armour. It is also a popular material, second only behind diamond and cubicboron nutride. Boron carbide’s unique crystal structure creates a strong covalent link. Its crystal structure consists primarily of orthorhombic Hexahedrons. This crystal structure is responsible for boron carbid’s excellent chemical and physical properties, such as its super hardness, low melting point, low density (low thermal expansion coefficient), high wear resistance, and high melting points. Because of this, boron carbonide exhibits high hardness.

Are boron and carbide toxic to our bodies?

Boron carbide has been called synthetic diamond. However, current research shows that it isn’t a health hazard. In order to create anti-neutron radiation fibers for leather, anti-neutron compounds, heavy metallic compounds, and polyester are mixed and spun. It is possible to get threads with a boron content of 35%. The fibre strength can range from 23-27CN/tex. You can use the breaking elongation to create knitted fabrics or nonwovens around the nuclear energy reactor. It can also increase neutron radiation protection shielding rates by up to 44%.
