Transition metal borides are compounds formed between transition metals and boron. These materials are known for their high hardness, thermal stability, and electrical conductivity. They often exhibit unique properties that make them useful in various applications, including cutting tools, wear-resistant coatings, and electronic devices. The structure of transition metal borides typically features a network of boron atoms interspersed with metal atoms, resulting in a strong and stable framework. Common examples include titanium boride and zirconium boride, which are studied for their potential in advanced materials science and engineering applications.
