Boron carbide

Boron carbide is a very hard, dense ceramic material made from boron and carbon atoms. It's known for its exceptional hardness, making it one of the toughest substances available, often used in industrial cutting tools, armor plating, and abrasives. Despite its strength, it is lightweight and resistant to high temperatures and corrosion. Boron carbide's unique properties stem from its crystal structure, which provides a combination of hardness, durability, and stability, making it valuable in applications requiring extreme durability and protection, such as military armor and advanced engineering components.
