بوريد

Also known as borides

A boride is a compound between boron and a less electronegative element, for example silicon boride (SiB3 and SiB6). The borides are a large group of compounds that generally offer high melting points and are more covalent than ionic. Some borides exhibit useful physical properties. The term boride is also loosely applied to compounds such as B12As2 (N.B. arsenic has an electronegativity higher than boron) that is often referred to as icosahedral boride.
