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.
