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.

硼化物是由硼和金属形成的化合物，广义上也包括硼和类金属、非金属形成的化合物。 硼化物的制备通常需要 1200–2200 °C 的高温。它们可以由硼和金属或其氧化物反应而成。它也可以由电解硼酸盐而成。 硼化物中，硼和金属的比例范围非常广阔，从有大量金属原子的硼化物（例如 M5B，M4B），通常为过渡金属形成的硼化物到有大量硼原子的硼化物（例如MB4，MB12甚至MB66），通常是碱金属、碱土金属、3族元素、镧系和锕系元素的硼化物。此外，硼化物中也有很多非整比化合物，含有不止一种金属原子。 硼化物的反应性低，熔点高。硼化物可用于生产高温电极、涡轮叶片、火箭喷嘴、燃烧室包层、中子辐射屏蔽和控制棒（硼的中子截面较高，可以吸收中子）。.
