PHASE EQUILIBRIUM IN CuSbS2-ErSbS3 SYSTEM
R.M.Agayeva

 

By methods of differential-thermal roentgenphase and microstructural analyses CuSbS2–LaSbS3 and CuSbS2–NdSbS systems have been investigated first and their state diagrams have been plotted. It is established that in the systems congruently melting compounds of Cu2LnSb3S7 composition are generated. On the base of roentgenstructural  analysis it is established that the compounds Cu2LaSb3S7 a=14.43, b=21.42, c=3.97Å; Cu2NdSb3S7a=14.463, b=21.404, c=3.962 Å crystallize in the rhombic syngony
