Boron carbide balls are ceramic balls made from boron carbide, a compound composed of boron and carbon. They are known for their high hardness, strength, and resistance to wear and abrasion. Boron carbide balls are used in various industrial applications, including as a grinding media in ball mills, as a valve and pump component, and as a ballistic armor.
