Literature data up to 1989 are given in the review by [1993San]. There is no phase diagram available for this system, but three intermediate compounds are known: Li3As, LiAs and Li3As7. Melting points of Li3As and LiAs are 550°C and 1000°C respectively [1959Tat], and a high temperature form was reported for Li3As in [1969Ben]. Two modifications have been also detected for the Li3As7 compounds [1996Bur].
