PHASE EQUILIBRIA IN THE PbLa2S4–PbBi2S4 SYSTEM
There have been studied phase equilibria and constructed T–x projection of PbLa2S4–PbBi2S4 system state diagram. Creation of quater sulfide PbLaBiS4 melting congruently at 1025 K has been establihed. Compound PbLaBiS4 has been crystallized in the orthorhombic syngony with parameters of elementary cell: a=1.170, b=1.451, c=0.412 nm s.g. Pnam, z=4
