B₂Ru is an intermetallic ceramic compound belonging to the ruthenium boride family, characterized by a hard, brittle crystal structure typical of transition metal borides. This material is primarily of research interest for high-temperature structural applications and wear-resistant coatings, where its extreme hardness and thermal stability could provide advantages over conventional ceramics, though industrial adoption remains limited due to processing challenges and cost considerations. Ruthenium borides are explored as potential alternatives to tungsten carbide in specialized cutting tools and as protective surface coatings in aerospace and high-performance industrial environments.
