What does «boruro» mean in Spanish?
- B3- anion
- Any binary compound that is formed by the combination of boron and some other less electronegative element, such as a metal, for example magnesium boride (Mg3B2) and silicon boride (SiB3 and SiB6). This is a large group of compounds that are usually high melting and covalent rather than ionic in nature. Some of these exhibit very useful physical properties. The term boride is also applied imprecisely to compounds such as B12As2 (Arsenic -As- has a higher electronegativity than boron) which is often referred to as icosahedral boride.
