The Cu2S–Cu7PS6–Cu6PS5I
quasiternary system was investigated by differential
thermal analysis and X-ray diffraction in combination with mathematical
modeling. The phase diagram of the Cu7PS6–Cu6PS5I
system, perspective views of the phase interactions in the ternary system, and
a projection of the liquidus surface were
constructed. New complex compounds do not form. The ternary system is of the
invariant eutectic type and characterized by the formation of limited solid
solutions. The three-dimensional one-, two- and three-phase regions present in
the Cu2S–Cu7PS6–Cu6PS5I
system are described.
