Zr2Co21B6

Zr2Co21B6 is an intermetallic compound combining zirconium, cobalt, and boron—a research-phase material belonging to the family of hard, high-melting-point intermetallics. This composition is primarily of academic and developmental interest for applications requiring extreme hardness and thermal stability, though it remains largely experimental and is not yet established in mainstream industrial production. The zirconium-cobalt-boron system is explored for potential use in wear-resistant coatings, cutting tools, and high-temperature structural applications where conventional superalloys reach their limits.
