Complex methods of physicochemical analysis have been used to study the nature of the interaction in the Nd-Pb-Te system along the Nd2Te3 section. For the first time, a state diagram of the Nd2Te3–PbTe section of the Nd-Pb-Te ternary system was developed. It has been established that two chemical compounds of the compositions Nd2PbTe4, Nd2Pb4Te7 and a narrow region of solid solutions based on PbTe are formed in the Nd2Te3–PbTe section.
