· Nb6 B4

Nb6B4 is a niobium boride ceramic compound belonging to the refractory metal boride family, characterized by a hexagonal crystal structure and extremely high melting temperature. This material is primarily investigated in aerospace and high-temperature materials research for applications requiring exceptional thermal stability and hardness; it competes with other refractory borides (such as HfB2 and ZrB2) for ultra-high-temperature structural applications where conventional superalloys reach their limits.
