In chemistry a boride's a chemical compound between boron and a less electronegative element. This's a very large group of compounds that're generally high melting and aren't ionic in nature. Some borides exhibit very useful physical properties. The term boride's also loosely applied to compounds such as B12As2 (N.B. Arsenic has an electronegativity higher than boron) that's often referred to as icosahedral boride. Ranges of compounds The borides can be classified loosely as boron rich or metal… (More on Boride)
