bonds with a less electronegative element. borides are all hard, high-melting-point materials with metal-like conductivity. they can be made by direct combination of the elements at high temperatures or, more usually, by high-temperature reduction of a mixture of the metal oxide and boron oxide using carbon
properties vary from one compound to the next, and include examples of compounds that are semiconductors , superconductors, diamagnetic, paramagnetic, ferromagnetic or anti-ferromagnetic. they are mostly stable and refractory. one such compound, lanthanum boride (lab ), is an inert refractory compound, used...
