摘要：

The concentration and temperature regions of the Pb5MoO8 compound are determined in the PbO-MoO3 phase diagram. The Pb5MoO8 is an incongruently melting compound with the temperature of decomposition 763 degrees C. The concentration and temperature regions are situated between 14 and 15.6 mol% of MoO3, and 744 and 763 degrees C, respectively. This part of the phase diagram is investigated by the slow cooling method of high temperature solutions and the temperatures of crystallization of the Pb2MoO5 and Pb5MoO8 phases are determined. The Pb5MoO8 single crystals are obtained by spontaneous crystallization for the first time. The possibility for growth of Pb5MoO8 single crystals in the PbO-MoO3 system is discussed.
