Radium Antimonide

Description

Radium antimonide could probably be prepared by the reaction of Ra and Sb metals. Ra melts at 700°C and is stable in an inert atmosphere until its boiling point of 1737°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 Ra metal at about 680 °C onto molten Sb metal.
However, this reaction has never been carried out due, perhaps, to the intense radioactivity of 226Ra atom. It is probable that Ra forms the same type of antimonide compounds as Ba but there is no industrial or commercial interest and no academic interest in these compounds due to the care required in handling such compounds.
