· Nb3B2

Nb3B2 is a niobium boride ceramic compound belonging to the refractory metal boride family, characterized by high melting point and hardness. This material is primarily of research and developmental interest for extreme-temperature structural applications, where its refractory properties and potential wear resistance could offer advantages over conventional superalloys in oxidizing or corrosive high-temperature environments. Engineers evaluate niobium borides for applications requiring materials that maintain strength and chemical stability beyond the capability of nickel-based or cobalt-based alloys.
