· Sc2 B4

Sc₂B₄ is a scandium boride ceramic compound belonging to the family of transition metal borides, characterized by a boron-rich crystal structure. This material is primarily of research and development interest rather than an established commercial product, being investigated for high-temperature structural applications where its refractory properties and potential hardness could provide advantages in extreme environments. Engineering interest in scandium borides centers on their potential use in aerospace, nuclear, and wear-resistant applications where conventional ceramics or superalloys reach performance limits, though widespread industrial adoption remains limited pending further process development and cost reduction.
