Crystal Structure of the New Quaternary Phase AgCd2 GaS4 and
Phase Diagram of the Quasi-Binary System AgGaS2 –CdS. — Alloys
of the title system including the new quaternary phase AgCd2 GaS4 are prepared
from the elements in evacuated quartz containers (1320–1420 K, 2 h, annealing
at 870 K for 500 h). The phase diagram is of eutectic type with the eutectic
point located at 37 mol% CdS and 1175 K. As revealed by powder XRD,
AgCd2 GaS4 crystallizes in the orthorhombic space group Pmn21 with Z = 16.
This phase melts congruently at 1284 K. — (CHYKHRIJ, S. I.; PARASYUK,
