BARIUM ANTIMONIDE

Barium antimonide can be prepared by the reaction of Ba and Sb metals. Ba melts at 727°C and is stable in an inert atmosphere until its boiling point of 1897°C is reached. 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 Ba-metal at about 780°C onto molten Be metal.
