Radium Arsenide Chemical Properties,Usage,Production

Description

Radium arsenide has not been prepared. It could be prepared by reaction of the elements. Ra melts at 700 °C (973 K) and the vapors of As could be carried into a reaction zone of 750 °C to form the compound. Yet, no record of this salt is available in the literature. Perhaps this is due the radioactive decay of 226Ra and the fact that no demand in industry exists. The reaction would be:
3Ra + 2As + heat ? Ra3As2
However, whether this compound exists and could be prepared remains unknown. It has no CAS number and there are no listed manufacturers of this salt.
