SUOYI Boron carbide powder B4C is a high-performance ceramic material that is widely used in many fields due to its unique physical and chemical properties. The following are its main features and typical applications:
Main features of boron carbide
1. Ultra-high hardness, Mohs hardness is about 9.3, second only to diamond and cubic boron nitride (c-BN), and is one of the hardest known man-made materials, suitable for use as abrasives and armor materials.
2. The density is only 2.52 g/cm³, which is lighter than most metals and ceramics, suitable for weight-sensitive military and aerospace applications.
3. Excellent wear resistance, outstanding wear resistance, often used to manufacture sandblasting nozzles, cutting tools and wear-resistant coatings.
4. The melting point is as high as 2450°C, and it can still maintain stability at high temperatures, suitable for high temperature environments (.
5. It is resistant to acid and alkali corrosion, but will be corroded by strong oxidants at high temperatures.
6. The main disadvantage is low toughness and easy to break, which is often improved by adding other materials (such as TiB₂, SiC) or sintering process.
