Terbium diboride (TbB2) is a ceramic compound belonging to the hexagonal boride family, characterized by high hardness and refractory properties typical of rare-earth borides. While primarily a research material rather than a commodity engineering ceramic, TbB2 is investigated for extreme-temperature applications and specialized cutting/wear-resistant coatings where rare-earth borides offer potential advantages over conventional borides in specific thermal or chemical environments.
