From Wikipedia, the free encyclopedia

The boride ion is B³⁻ (a boron atom plus three electrons).

A boride (compound) is a compound that has boron with more electropositive elements.

[edit] Examples

• lanthanum hexaboride (LaB₆)
• magnesium diboride (MgB₂)
• magnesium tetraboride (MgB₄)
• titanium boride (TiB₂)

[edit] Discussion

Some borides have some ionic character, but many (such as titanium boride) are inert compounds with high melting points similar to titanium carbide. Lanthanum hexaboride (LaB₆) finds application in the electronics industry.
