Application method of boron carbide in iron trough castable During the communication with refractory customers, I learned that some customers would ask that boron carbide does not play a big role in iron trough castables. What is the reason? The reason is very simple. It may be because they use the no-baking type. The no-baking
Boron carbide is mainly used in carbon-containing refractories to have an anti-oxidation effect. It can densify the product and prevent the oxidation of carbon in carbon-containing refractories. At the same time, with the columnar crystals generated and is distributed in the refractory In the crystals and gaps, the porosity is reduced, the medium temperature strength

Boron carbide, also known as black diamond, is an organic substance with a molecular formula of B₄C, usually gray-black fine powder. It is one of the hardest materials known (the other two are diamond and cubic boron nitride). It is used in tank armor, bulletproof vests and many industrial applications. Its Mohs hardness is 9.3.
Boron carbide (B4C), also known as black diamond, has a molecular formula of B₄C, usually gray-black powder. It is one of the hardest materials known in armor, bulletproof vests and many industrial applications. Its Mohs hardness is 9.5. It was a by-product of metal boride research in the 19th century and was not scientifically studied
