Beryllium antimonide has been prepared by the reaction
of Be and Sb metals. Be melts at 1287°C and is stable
in an inert atmosphere until its boiling point of 2469°C.
Since Sb melts at 630.6°C and is stable in an inert atmosphere
until its boiling point of 1587°C, the reaction is
best carried out by evaporating Sb metal at about
1600°C onto Be metal.
