A review of the As-Lu system by [1986Gsc1, 1986Gsc2] includes literature data up to 1985. No other relevant work exists on the As-Lu system. Only one LuAs compound has been found. Crystal structures of solid phases are listed in Table 1. The schematic phase diagram assumed by [Moffatt] supposing similarity to other As-rare earth systems was accepted in [Mas2] and remains unchanged (Fig. 1). The assumed invariant equilibria are reported in Table 2.
